This is especially true on cars with a leaking valve cover gasket where the oil has contamintated the rubber boot and the electrical parts inside. This boot can be replaced on its own without having to buy a whole new coil. This part is also useful if you purchased a coil that did not come with a new boot.

This boot works with the 12131748018 ignition coil only and fits the vehicles listed below.

Sold per boot/per coil.
