Magnecor Race Wires are primarily designed and constructed to be used in applications where it is essential to prevent the possibility of ignition wires compromising engine performance. Modern race engines, modified street engines and stock street engines which rely on electronic devices to control the function of either or both the ignition and fuel systems are prone to interference from all other spiral conductor ignition wires sold through performance parts outlets, none of which can provide proper suppression for EMI, particularly if a high-output ignition system is used.
Magnecor always recommends the use of Race Wires for any stock or modified late model street engine that is electronically managed, however, most other modified or street engines can also use Magnecor Race Wires to improve ignition performance.
*Note - All 3SGTE spark wires fit and work across the generations as long as you use the appropriately sized distributor cap (which need to match your igniter). '91-92 Gen2 engines have the "large pins". The 93+ and Gen3 engines have the "small pins" from the factory.
