1985-1991 Distributor Cap 4 Screws Type ACDelco - OEM Number(s) (19110932)

Restores reliable ignition performance with OE-style ACDelco distributor cap.

A weak or misfiring distributor cap can be tricky to diagnose, but it’s often the hidden cause of poor ignition performance. This ACDelco distributor cap is the correct 4-screw style used on 1985–1991 Corvettes. Built to OEM standards, it delivers consistent spark distribution to keep your engine firing smoothly.

Before ordering, confirm your Corvette uses the screw-fastened style cap. Some models use the alternative spring-loaded, quarter-turn clamp design.
