Standard Ignition Distributor Cap P/N:JH-77
Keep high-voltage spark moving to each cylinder with the Standard Ignition Distributor Cap JH-71, a direct-fit replacement from a global manufacturer of original equipment ignition products. It fits many vehicles, among them the 1976-1979 Toyota Corolla, 1989-1990 Chevrolet Tracker and 1989-1990 GMC Tracker. See the Buyer's Guide tab for the full list and engine details.
The distributor cap covers the distributor and holds the terminals that the spinning rotor passes. It directs voltage from the ignition coil to each spark plug wire in firing order. Over time a cap can crack, build carbon tracks or corrode at the terminals, and any of these may contribute to misfires or hard starting.
If a worn cap is behind your ignition trouble, replacing it with JH-71 helps restore a clean path for spark. When you install it, move the plug wires over one at a time so that each wire lands in the same tower position it held on the old cap.
