It can be a tall order, but those are the qualifications for a good set of spark plug wires. Solid Core: Solid core spark plug wires typically utilize stainless steel or copper, which conducts electrical current very well. This Pro Spiro wire measured 4 -feet long and as you can see generates 1,661 ohms of resistance. As an example of how reduced-resistance can improve performance, we tested a small-block street car with a four-gas exhaust-emissions analyzer and measured a reduction in hydrocarbon (HC) along with an improvement in CO2 levels, just by reducing the resistance in the spark plug wires. It recently expanded its line to include Vertex Magnetos. The advantage to the larger O.D is to protect the core and insulate it from arcing through the jacketing.. The core is the same diameter, regardless of the wire O.D. The number one job of any spark plug wire is to transfer an electrical charge from your ignition to your spark plugs. Were told the ceramic coating acts as a heat mirror, reflecting infrared energy and heat away from the plug boot. Youll see a lot of diameter measurements thrown around regarding plug wires.
Spark plug wires are commonly direct-fit to work on a specific application. Thoughts on Granatelli spark plug wires. This is important to be aware of because each field can create interference with more sensitive electronic components. A: The main reason for heat socks is to minimize heat damage to the spark-plug-wire boot from melting because of its proximity to a header tube or cast-iron manifold. Commentdocument.getElementById("comment").setAttribute("id","ab69b10f9f62d942e08412c7b80c51f4");document.getElementById("g3a58ea9af").setAttribute("id","comment"); We love driving, and love sharing tips with other drivers on how you can diagnose, fix and improve your car. For instance, 7mm, 8mm, 8.8mm, and 10mm are typical wire diameters. When that is taking place, an electromagnetic field is created. Electro-magnetic interference (EMI) or radio frequency interference (RFI): Asthe higher charges of todays electronic ignitions are moved through the wires, an electromagnetic field is created around the wire. Ugh, don't necro a 14 year old thread. On the right is the older female socket where the male connector is attached to the plug wire. to fit your particular needs. To make sure the Number 8 wire doesnt melt on the header tube, we may reroute it underneath the header tube. However, thicker wires, like these Moroso Super Max II 11mm wires, can provide added RFI suppression and insulation. A: StreeThunder is a good economy/daily-driver wire set, while our Spiro-Pro line is suitable for everything and is the most popular choice. Without spark plug wires, you might as well forget about getting to work!
Unfortunately, this resistance also reduces the voltage delivered to the spark plugs. Mild dimples even close to the head will not cause a loss of power.
| . The extreme heat and heavy loads of voltage they have to endure on a routine basis compromise their functionality and make them weaker with the passage of time. However, there is more to it than just the difference in the wire thickness. Measuring plug wire resistance is very easy with the help of a hand-held volt/ohm meter. This minimizes the hydrocarbon and carbon monoxide numbers. The Extreme 9000 plug wire kits utilize ceramic boots that will withstand temperatures up to 2,000 degrees. David Fuller is OnAllCylinders' managing editor. Be cognizant of the resistance in ohm/foot and of EMI or RFI. Most Taylor wire kits come with both sets of distributor cap connectors. Reducing HC (unburned hydrocarbons) means more of the fuel is burned during idle. This is one reason why the OEs eventually went to coil-near-plug ignition systems to reduce the length of the spark plug wires thus further reducing resistance. Crimson_Tide: I meant to say plug WIRES. If we divide 2,000 by 2 we get 1,000 ohms of resistance per foot. We will safeguard your e-mail and only send content you request. Plug wires are most often rated by their diameter. If the area next to the boot is too tight, the best solution is to dimple the tube to create sufficient clearance. Does size matter? In addition, carbon corebreaks down more quickly than other materials so they require relatively frequent replacement. Are all d16 and d15 sohc plug wires the same. Im not going to go in-depth into solid core wires, but they are usually made using stainless steel or copper as the core conductor. Super Max II spark plug wires have two fiberglass braid layers and an intermediate silicone-EPDM layer for extra insulation, giving them a larger diameter. Are You Ready? Connect all the remaining spark plug wires one by one, according to the firing order of the repair manual. As an example, if you have 4-feet of Super Stock 5000 or Street Fire wire, you should have an ohm reading of 2,000 ohms. Make a note of the wires resistance. A: The most common is the male post on an HEI distributor. Our silicone-blend material rates at 500-degrees F, while our EPDM synthetic rubber measures 450-degrees F. There are two primary distributor-cap plug wire connections in use today. An accomplished engine builder and technical expert, he will focus on the tech-heavy content that is the foundation of EngineLabs. While a spark plug wires job might appear simply to transfer high voltage to the spark plug, this can and does require some sophisticated engineering. Spiral wound wires are a mainstay on any high-performance ignition system. Every complex machine is composed of several components that work in conjunction to make the whole machine operational. The boots are available in straight, 45-, or 90-degree configurations. Two; whenever possible, route the wires away from sensitive electronics.. With the plug wire removed from the engine and your test meter set to ohm (). Contact Us -
The thicker wire diameter provides a wider margin of safety to prevent voltage leaks. As mentioned in the introduction, even something as simple as a spark plug wire incorporates a tremendous amount of engineering.
