Send ignition-coil voltage to the right cylinder with the ThunderSpark Distributor Cap 925-1011, an OE-replacement cap that drops into the original distributor housing. It's a direct-fit replacement for a wide range of 1985-1996 GM vehicles, including the Chevrolet Astro, Camaro, S10 and S10 Blazer, GMC Safari, Sonoma, and S15 Jimmy, Oldsmobile Bravada, and Pontiac Firebird — see the Buyer's Guide tab for the full list of applications.
A distributor cap directs high-voltage current from the ignition coil to the correct spark plug through the rotor and its internal terminals. Over time a cap can develop carbon tracking, cracks, or corrosion, which may lead to misfires, hard starting, and drivability issues.
- Directs High-Voltage Spark: routes ignition-coil output to the correct cylinder for the proper firing order.
- OE Replacement Quality: built to meet OE specs for terminal alignment, dielectric strength, and conductive-path precision.
- Heat-Resistant Materials: high-dielectric compounds designed to withstand high voltage, thermal cycling, and engine vibration.
- Exact OE Fit: designed to install into the original distributor housing and maintain secure contact with the rotor and ignition wires.
If a cracked, carbon-tracked, or corroded cap is the cause of your misfire or hard start, this cap replaces it as part of a tune-up or ignition repair.
