Common Replacement Reasons

• Engine misfire caused by worn ignition wires

Installation Notes

Verify terminal style, boot angle, and wire routing against the original equipment layout before installation. Route the wires away from hot exhaust components and moving parts, and confirm each connection is fully seated at the spark plug and distributor or coil end. For best results, replace wires one at a time to preserve firing order during service.
