If your exhaust manifolds or headers don't offer a lot of clearance for the plug wires, MSD's Pro-Heat Guard will provide the extra protection you need. This tough sleeving is made up of a thick glass woven core that resists temperatures up to 1,000°F. A silicone rubber coating surrounds the core adding protection against abrasion and heat. The sleeving has a 3/8" inner diameter so it easily slides over most spark plug wires. Availability: Usually ships the next business day. 3411$83.99 Don't see what you want? .......... Need help?
