Spark Plug Wires

Spark Plug Wires have a limited life. We normally see deterioration and/or mis-firing by at least 60,000 miles. Mis-fires can be evident using a high quality Timing Light or a diagnostic scope, even when not noticeable during normal driving. New wires should be installed as a normal maintenance item every few years, or at 50-60,000 mile intervals.

MAGNECOR SPARK PLUG WIRES
These are excellent high performance ignition spark plug wires. The construction is top quality and waterproofing is achieved by tight fitting boots over the silicone jacketed cables. They are designed to handle all ranges of ignition systems - from stock to high energy full race. Suppression levels are high enough to not foul radios or on-board computers. Cables have service temperatures of 600 degrees (8.5mm) and 700 degrees (10mm). Spark Plug boots can tolerate 600 degrees. Color choice is red. The 10mm wires have the added protection of thicker silicone jacketing, in addition to looking great on any engine.

"ULTRA RED-HOT" WIRES"
These excellent 8mm silicone jacketed wires are assembled by Racing Beat. The resistor wire design incorporates metal-covered wire, with a sealed wire-wound resistor at the end of each wire. For maximum radio suppression, early sets are also available with metal spark plug shields. "RACE" wire sets are designed with greatly reduced resistance for maximum spark intensity. These are intended for racing purposes only, and will result in considerable radio interference if used on "street" cars.
