This is a difficult question to answer, and is in fact one of our most frequently asked questions, but in general you can use any spark plugs with Magnecor Race Wires. On a full race engine, spark plugs specifically designed for racing should be chosen. A decision as to which type and brand should be made only after investigating which spark plug is used by other competitors racing engines and vehicles similar to yours.

Most forum members agree that the stock Champions are just as good under most conditions as considerably more expensive plugs, including Bosch Platinums. Some have said that the "performance gains" claimed by some are due only to the use of new plugs, rather than special new plugs. The best oil is synthetic - it provides more protection during cold starts, when most engine wear occurs, and is more durable than standard oils.

If you have a 2000-2004 Isuzu, make sure you only use Denso K16PR-P11 spark plugs. Check the link below to buy them for 6.80/plug (note the dealer charges about 17/plug) If you have a 2000-2004 Isuzu, make sure you only use Denso K16PR-P11 spark plugs. The 2000-2004 engines have the GM/delphi "ion sensing" ignition system where the spark plugs are used as a sensor (when they are not firing) to measure the electrical resistance of the gasses in the combustion chamber.

The price you pay for Magnecor Race Wires can seem reasonable or surprisingly inexpensive for owners replacing original equipment ignition wires. The design and complexity of engines fitted to new production vehicles in recent years has come to rival the engines that were once only available in expensive exotic cars.

The conductors used in all Magnecor ignition cables will outlast the life of the engine unless deliberately severed. The life of ignition wire assemblies relies entirely on the ability of the owner and/or installer to install the wires correctly (particularly on engines designed to make it impossible to easily reach spark plugs), and the need to attach the wires to spark plugs and distributor/coils which are in good working order.

Indmar has not tested and cannot approve the use of split fire spark plugs. Incorrect spark plugs can foul, cause radio frequency interference, cause the engine to run poorly, and may cause severe engine damage from detonation. Your warranty does not cover damage caused by the use of products not recommended by Indmar. The operator lists the recommended spark plug for your engine.

Professional race engine preparers do not use Magnecor Race Wires to increase engine horsepower — they use them to maintain full engine horsepower.

Although this problem is not common, it is an irritation for owners of the vehicles concerned. From our experience, after working with vehicle owners to solve this problem, we offer the following suggestions as to why this problem occurs: The most common cause.

Most definitely. We have found that the best spark plugs to use are standard copper core plugs such as Autolite. Double platinum plugs burn too cool. Standard plugs burn at a higher rate which this system needs. And, at the same time, you are saving money because the copper plugs are less expensive. In the newer vehicles Iridium spark plugs are also acceptable.

Most battery plugs are very inefficient in use and racers want to squeeze every bit of power out of their motors and batteries. Soldering the wires directly to the motor and/or battery instead of using plugs is one way to regain some of the lost battery power. There are a couple of types of plugs that lose almost no power, however preassembled battery packs aren't equipped with them.

Magnecor KV85 Competition (8.5mm) and Magnecor R-100 Racing (10mm) Ignition Cables are primarily designed for modern race and modified production vehicle engines that use computerized engine management systems and high-output ignition systems. Magnecor's exclusive Metallic Inductance EMI Suppressed 2.

Both the VE and VG use the NGK plug as a stock spark plug. The VE requires a platinum plug, which can run fairly expensive, at about $9/plug. I don't have the part numbers for this plug yet. The VG also uses an NGK plug, but they are non-platinum and cost just over $1/plug. Part numbers: Standard Type BKR6ES-11; Hot Type BKR5ES-11; Cold Type BKR7ES-11; Plug Gap 0.039 - 0.043 in (1.0 - 1.1 mm). Check your coolant level. this is a common problem.

You may use either the aircraft or automotive spark plugs. There are several hundred airplanes running the EIS with automotive plugs. Additionally, you must verify that the heat range of an automotive plug is correct for your engine or you risk causing severe damage. We prefer, however, the aircraft plugs as they have been designed to work with aircraft engines and do not require any modifications for installation.

Mike Jukes uses the NGK 4 prong type which he thinks in theory are better than splitfires and they seem to work. Roy Tomlinson says try Bosch Super 4's as they've passed his doorstep challenge. They do work and make the car feel a bit crisper!
