Keep spark reaching the right cylinder with the ThunderSpark Distributor Cap 925-1019, an OE-replacement cap for conventional distributor-based ignition systems. It drops into the original distributor housing on a long list of Ford, Lincoln and Mercury applications — including the 1978-1996 Ford Bronco, 1976-1996 Ford E-150/E-250/E-350 Econoline, 1979-1995 Ford Mustang, 1977-1996 Ford F-150/F-250, 1981-1991 Lincoln Town Car and 1977-1991 Mercury Grand Marquis. See the Buyer’s Guide tab for the full list of 96 applications and engine details.
The distributor cap routes high-voltage current from the ignition coil to the correct spark plug through the rotor and internal terminals. Over time, caps can develop carbon tracking, cracking, or corrosion, which may lead to misfires, hard starting, and drivability issues.
- OE Replacement Quality: Built to meet OE specs for terminal alignment, dielectric strength, and conductive-path precision.
- Heat-Resistant Materials: Made with high-dielectric compounds to withstand high voltage, thermal cycling, and engine vibration.
- Exact OE Fit: Designed to fit original distributor housings for secure, reliable contact points.
- Directs High-Voltage Spark: Sends ignition coil output to the correct cylinder to maintain the proper firing order.
If a cracked or worn cap is the cause of your misfire or hard start, this replaces it.
