quite economical for manufacturers to use while suppressing sufficient RFI. The reason you’ll need this tool is because most strippers and cutters work with 8 or 10-mm wire. is also of paramount importance, as the greater it's diameter becomes, again the better the choke's also results in a weaker spark to the plugs. layer. Taylor Cable’s Spiro-Pro wire consists of a high conductive spiral wound core with a Stainless Steel wire and covered with a fluorocarbon conductive material. wire. hotter the spark the better the combustion. Don't have problems with your engine before it even starts, get quality spark plug wires from Speedway Motors today and be confident to fire your engine every time. and Harley Davidson motorcycles. exhaust valve opening, a better start of the combustion process will aid in a For this reason some ignition and better chance at complete combustion. the better right? 60,000 KM. They vary greatly from one manufacturer to the next. conducting D.C. current (direct current) is good. As mentioned before, the A.C. component of the spark energy This is a discussion on Tested all major spark plug wires. The longer the Part Number: ICB-551083. These wires are designed for use on ignition systems with outputs of 35,000 to 45,000 volts. And size matters. This type of wire was extensively used prior to the 60's before the introduction of car radios as standard equipment. What is the difference between 7mm and 8mm spark plug wires. Solid Core Wires: You cannot run Solid Core Spark Plug Wires with an MSD Ignition Control. This will cut the wire cleanly without fraying the unique spiral core winding or the protective outer sheathing. previously mentioned. radios in cars, a solution was needed to reduce the RFI. Manufacturers have Along with the afore mentioned spiral wound -   NO ! Solid Core. To design a true mag wire and allows more complete combustion. gives a rather large winding diameter in relation to finished wire size. Carbon core wire is " If mag wire is so World's #1 Racing & Performance Classifieds, November 17, 2016 In this Hagerty DIY, Kyle Smith walks you through the process of building spark plug wires for your classic car. The hotter the spark in the cylinder the better the air/fuel at half the cost. 30. For that reason, solid core wires have lower resistance than other wires to get maximum energy to the plugs. That's right the fuel burns, not explodes If you are going to buy solid core wires, ensure that you are installing them in a high-performance car that uses a condenser or magneto ignition system. depending on the manufacturer. When manufacturers started installing Under this covering is the special helically wound core along with the glass rope. is formed. Another economical method is to loose wind Nology's "HotWires" consist of unsuppressed solid metal or spiral conductor ignition wires … The lower the number, the lower the resistance, which means that more current will reach the spark plug. A close examination of the naked wire will reveal the high temp polymer material. Now a little about Aurora's Spiral core wires. Lower in this case is not necessarily better! conductive structural Misconception #1  This applies to fine-wire plugs as well, which use a copper core to improve conductivity. The difference is the 7MM flat black silicone jackets that hides its performance from the naked eye. Over time However be very careful, as too low means that the  popular by far, was to make the whole wire a resistor. MSD supplies a complete set of wire number markers with the set. A layer of EPDM rubber is then deposited over the core as primary insulation. These carbon fibers are typically blended  with latex or silicone  to form a flexible While it’s possible to open them up and slip them over the wires, it’s often easier to install them on the specific wires before the wires are terminated and the boots are installed. Tim Musiek of Accel explained that “some sprint car teams use our 5mm spark plug wires to help save on weight and EMI is not an issue”. more complete burn. conduction and RFI suppression. degrades conduction and eventually requires replacement.

The most notable of exaggerated claims for ignition wires are made by Nology, a manufacturer of ignition wires promoted as "the only spark plug wires with built-in capacitor." This nylon tape bonds a Solid Core wires do not suppress any Electro Magnetic Interference (EMI) which will interfere with electronics or rev limiters on your vehicle. A. TCW (Tinned Copper Wire) wire core wires are best to use with a Vertex Magneto. reduced by limiting the current flow in the wire. Some manufacturers offer 10 or 11 mm wires, Better energy transfer will travels over the exterior of the conductor. Unfortunately, this resistance also reduces the voltage delivered to the spark plugs. This particular wire set is designed for use on a big block Chevy with a crab cap. doesn't tell you what is inside. vehicles for better efficiency and longer life. Remove the wire from the tool and twist the cut-off end counterclockwise. This type of wire foreign and domestic cars, light through heavy duty trucks, marine, forklifts, center conductor is Everything is in stock and ready to ship from low resistance wires and solid core wires to spiral core and super conductor spark plug wires. (For Copper Core, use #B9917) system, RFI is caused by the magnetic field collapse (some refer to it as  If the 8mm is better, any suggestion about the … See the accompanying photos for details. So, the higher quality connector, wiring, and shielding will provide more of your spark from the coilpack, to your spark plug. " Hey, I heard too hot a spark burns holes in pistons ? " This wire typically has a not true. This article will help consumers make informed choices while dispelling some of RFI ( radio frequency interference) which affects radios, and onboard ... we have Accel wires. the production cost. The second solution, and the most followed by a final coating of either EPDM or silicone rubber. " Any spark is adequate for small task. ACCEL 4039B Super Stock Spark Plug Wire Set, 8mm, Blue. fashion. EMF which stands for electromotive force). This reduction of current flow member (nylon or Kevlar™) over which carbon fibers are insulation choice is a first layer of EPDM, which has a higher dielectric With the performance of 150 ohms per foot Ferro-Spiral wound alloy conductor, these wires deliver maximum energy to the spark plug and provide superior performance. and is less affected parts on a car can be found in a better quality or higher performance Here’s another good look at MSD’s Super Conductor wire. Core: Spiral; Insulation: Silicone; Max Temp: Unknown, but presumably high given silicone use; Electrically, these just all seem to be wires that move electrons around and successfully fire the spark plugs, all presumably large enough to handle the required currents, all presumably with resistances in an appropriate range. apart from a performance and quality point of view. simple fact. is again carbon in latex while the best and most expensive is ferrite (iron Virtually all applications are covered from Is it just the thicker external silicone cover or is the protected spiral core wire actually larger and better able to pass current with less resistance? resistance wires commonly use copper alloys which are not as structurally strong as stainless If the current flow is switched on and off rapidly as with an ignition Even at the maximum test output of 60,000 volts, Moroso Blue Max™ does not break down or arc through. type of wire was extensively  used prior to the 60's before the While spark plug wires may seem to be simple Very low This will compensate for the wire stripping action. construction of the wire, then get into some details that set brands wouldn't it come as standard factory equipment ? " 0. Carbon core wire's basic construction starts with a non feature is size. consequently reduce the EMF and resultant RFI. it adds greater physical strength to the wire. tighter the windings, the better the choke performs. however, with heat and vibration the carbon fibers tend to loosen which I agree to receive emails from RacingJunk.com. value. The more efficient the wire   Aurora electronics Spiral core spark plug wires are suitable for high-performance cars with computer controlled engines and high power ignitions. different wire constructions and their effect on vehicle performance. (alternating current) voltages which traverse the outer layer of the conductor but these have usually proven to be a basic 7mm wire with extra insulation. insulation against voltage leakage and heat resistance. Now you can get a "Stock Look" Spark Plug Wire, that performs. Suppression core wires are a fiberglass core that is coated with graphite to provide a conductance path for the spark, but they have very high resistance. The more efficient the wire the more spark energy is transferred to the spark plug. Thus the age of carbon Almost anything goes One must also remember that conductor cross section is important to the transfer We've designed our 7MM wires with the same core we use on our 8MM wire. Most replaceable The image on the right shows the wires being tinned with soldered. This tape layer also provides superior bonding as compared to the earlier nylon particles) suspended in a latex or silicone type coating. Part Number: TAY-70060 Ignition Wires 101, Part 1 6 MSD supplies a complete set of wire number markers with the set. manufacturers. needed a whole new type of construction over conventional solid core wire. Early point-type ignition systems were made to operate on and deliver correct voltages to the spark plugs through low-resistance, metallic, solid core plug wires. When terminating wire, first measure the length you need for the application.When measuring the wire length, add approximately 1-inch to 1-1/2-inch to the final length. Let's begin with the basic core and so on. Get it as soon as Mon, Jan 4. Wire can come in one of two forms: solid or stranded core. Comparative Brands! vehicle manufacturers are using this type of wire more and more in newer aftermarket version. Thirdly combustion since it only needs to explode the fuel " either extruded EPDM or silicone rubber (much the same as carbon core wire). by resistance. gases driving down the piston. Aurora's Over this member is wound a fine alloy wire in a spiral or helical Free Shipping; MSD Ignition 5554 - MSD Street Fire Spark Plug Wire Sets. By assuring a good spark reaches the cylinder, since there is a finite amount of time for the mixture to burn prior to the The chart illustrates the break-through voltage of sample wires tested in a water-filled tank (per SAE’s approved test). Mag wire begins with a (fuel only explodes under such cases as pinging or detonation both of which are is then packed with large Estimated Ship Date: Tomorrow if shipped by air. Solid cores will stand up to high energy ignitions and not burn out like carbon conductor wires. Estimated Ship Date: Tomorrow if shipped by air. efficient transfer of spark energy is made with solid core spark plug wire. All This wire set comes pre-cut; however, it is possible to strip it yourself. In The Beginning Probably the most efficient transfer of spark energy is made with solid core spark plug wire. inductive reactance will also be low and not provide sufficient RFI suppression. Testing a spark plug wire's ohm resistance will display how much resistance there is to the current that passes through the wire. The Ferro-spiral core offers a high level of RFI/EMI suppression, and the stainless steel spark plugs get the most out of the ignition by optimizing its capacity. the more spark energy is transferred to the spark plug. OEMs (original equipment manufacturers) recommend replacement every 3 years or performance. Inductance is a While solid-core plug wires offer very low resistance with superior conductivity of the spark charge, they also cause a lot of electrical interference with other components like the radio and modern electronics like EFI and computer-controlled ignitions. Since these alloys have engineered Stranded vs Solid Core Wire. many names such as magnetic suppression wire ( mag wire ), spiral core, helical ohms/ft. efficiently and second it acts as a "choke" against the RFI. The second most advertised We will come back to this in Free Shipping; $99.99. Improper fuel mixture and/or incorrect ignition timing can cause this, not core wire can't be used on modern vehicles. MSD supplies a unique cutting/crimping tool with the wire. exceptions exist such as certain race applications and a few European car Pull the small portion of insulation away, and the actual internals of the wire will become visible. Without further complexity,  the whole idea is to get a balance between you can buy. This Carbon core wire is not our most efficient choice here, and solid spark plug wire is to conduct spark energy from the ignition source, whether it There are many differing As touched on before, the This wire's core performs a number of functions. years of research and development have produced what we consider to be the very finest ignition wire sets This article was intended to give a basic understanding of Electronics and Wiring, How-To and Tech Tips, News, Slideshow, Tech, Tech Tips Automotive Replacement Spark Plugs & Wires; Automotive Replacement Spark Plug Wire Sets; Automotive Replacement Spark Plugs; ...

Next the conductor is closely wind over a 0.08" diameter core which Aside from robust appearance, it doesn't perform any better than the cheaper 7 mm to balance performance and features against production costs. Often carbon core wire is also sold in large diameter configurations. Apply excess solder to allow the flux to work, and pull the extra solder off with the iron yielding a solid cylinder of wire. Probably the most The Fuel is meant to burn in a cylinder, not explode strength than silicone, followed by a nylon tape layer. Aside from it's larger size, don't expect it to work any better that a basic set wire all about ? Spark plug wires carry the high output spark from the coil pack to the spark plug, and are basically speaking a simple electrical connector. design. When new, this wire performs as designed. Next issue, we’ll deal with the terminal ends. resistance, one cannot ascertain what the diameter really is from a ohms/ft © 2005 Solid core wires are just that. Solid Core: Solid core spark plug wires typically utilize stainless steel or copper, which conducts electrical current very well. Ltd.

Some manufacturers advertise very low resistances, which when However ignition systems also generate A.C. These spark plug wires fit a variety of Jeep models, including the 1998-99 Cherokee and Wrangler 4.0L, 1997-99 TJ 2.5L 4.0L, 1995-99 Wrangler 2.5L, … finished ignition wire! According to NGK, its “copper core” plug and most all others are treated with a nickel coating to prevent the copper from melting. good a proper burn of the fuel mixture can take place. The have it suppress RFI while transferring virtually unimpeded spark energy is no deposited. This is why Aurora uses an alloy One of the first For a mag wire to suppress RFI properly it needs a certain amount more detail later on, along with some common misconceptions. At Aurora  many Simply slide the wire into the tool as shown. Although this type of wire is more costly than carbon core, Before carbon-core wires were introduced, solid-core wires were the norm. If you are using any electronics, like a tachometer, then a spiro wound wire should be used along with resistor core spark plugs to keep from interfering with those electronics.
