Route high-voltage spark to the right cylinder with the ThunderSpark Distributor Cap 925-1031, a direct-fit replacement for the 1983 and 1985-1988 Nissan Sentra, 1989-1990 and 1993-1997 Nissan Tsuru, 1988-1989 Subaru GL, 1987-1989 Subaru GL-10, 1990-1994 Subaru Loyale, and 1988-1989 Subaru XT. On vehicles with conventional distributor-based ignition systems, the cap directs current from the ignition coil to the correct spark plug through the rotor and internal terminals. See the Buyer's Guide tab for engine details.
Over time a cap can develop carbon tracking, cracking, or corrosion — signs it may need replacing include misfires, hard starting, and drivability issues. If a worn or cracked cap is the cause, this replacement helps restore consistent spark delivery.
