Good To Know

Q: Does the kit include gaskets or mounting hardware? A: No, it includes only the coils, spark plugs, and wires; reuse existing seals and hardware from your vehicle.

Q: How often should the spark plugs and wires be replaced? A: Iridium plugs can last up to 100,000 miles under normal driving, but inspect wires for cracking at each interval and replace the set if resistance exceeds factory spec.

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