Good To Know

Q: Should ignition coils, plugs, and wires be replaced at the same time? A: Yes, replacing these components as a complete set ensures balanced electrical resistance and prevents premature failure of new parts.

Q: Do these coils come pre-greased? A: It is recommended to apply a small amount of dielectric grease to the boot interiors during installation to prevent sticking and moisture entry.

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