Specs At A Glance

Good To Know

Q: How can I tell if my vehicle uses square or round coils? A: You must inspect your current coils visually, as square coils have a distinct flat, blocky shape compared to round-style coils.

Q: Are the spark plugs pre-gapped in this kit? A: While they are pre-gapped at the factory, it is always recommended to verify the gap setting matches your engine manual before installation.

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