Specs At A Glance

Good To Know

Q: How often should spark plug wires be replaced? A: Most LS-family ignition wires are replaced around 60,000 to 100,000 miles, or sooner if the engine misfires or the insulation shows cracks.

Q: Can I install these with basic hand tools? A: Yes, the wires pull off the coils and plugs by hand, and routing them one at a time prevents mix-ups.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
