• Rugged insulation: a 450°F-rated silicone jacket is extruded over a tightly woven fiberglass braid, applied over high-dielectric-strength EPDM inner insulation for performance that exceeds SAE specifications.
• Silicone 90° boots: silicone spark plug boots with a 90-degree boot angle that meet or exceed OE boot temperature rating.

Spark plug wires carry high-voltage current from the distributor or coil to the spark plugs; cracked, brittle, or high-resistance wires can cause misfires, rough running, and hard starting. If worn wires are the cause, this set replaces them. Country of origin: China.
