Route high-voltage spark to the right cylinder with the ThunderSpark Distributor Cap 925-1050. It installs as a direct-fit replacement for the 1998 Chevrolet Tracker, 1996-1997 Geo Tracker, 1996-1997 Pontiac Sunrunner, 1996-1998 Suzuki Sidekick, and 1996-1998 Suzuki X-90 — check the Buyer's Guide tab for engine-specific details.
In a conventional distributor-based ignition system, the cap directs high-voltage current from the ignition coil to the correct spark plug through the rotor and its internal terminals. Over time, caps can develop carbon tracking, cracks, or corrosion, which may lead to misfires, hard starting, and drivability problems. This OE-replacement cap is built to OE specifications for terminal layout, dielectric strength, and conductive-path precision.
If a cracked or worn cap is the cause of your misfire or hard start, replacing it helps restore proper spark delivery.
