Keep high-voltage spark headed to the right cylinder with the ThunderSpark Distributor Cap 925-1076, an OE-replacement cap for conventional distributor-based ignition systems. It fits many vehicles, among them the 1975 Ford F-150 5.0L / 5.9L / 6.4L / 7.5L, 1964-1973 Ford Mustang 4.3L / 4.7L / 5.0L / 6.4L / 7.0L and 1975 Ford F-250 5.9L / 6.4L / 7.5L. See the "Vehicles it fits" section for the full list and engine-level fitment.
The distributor cap takes high-voltage current from the ignition coil and sends it to the correct spark plug through the rotor and its internal terminals. Over time a cap can develop carbon tracking, cracks or corrosion, which can lead to misfires, hard starting and drivability problems. If a worn cap is the cause, this unit replaces it, either as part of a tune-up or during an ignition system repair.
- Directs high-voltage spark: Routes ignition coil output to the correct cylinder to maintain the proper firing order.
- Designed for original housings: Made to fit the original distributor housing for a secure seal and reliable contact with the rotor and ignition wires.
- Built to OE specs: Built to OE specifications for terminal alignment, dielectric strength and conductive-path precision.
- Heat-resistant construction: The plastic cap is designed to handle high voltage, thermal cycling and engine vibration.
Specifications: The cap has nine vertical towers and female terminals, and it is black. This listing is for one cap, and the listed applications use one cap each. Country of origin: China.

What does a distributor cap do?
It carries high-voltage current from the ignition coil to each spark plug lead through the rotor and internal terminals, which helps keep the firing order correct.
What are signs a distributor cap may need replacing?
Carbon tracking, cracks or corroded terminals can cause misfires, hard starting and drivability issues. Other ignition parts can cause these symptoms too, so diagnose the cause before replacing the cap.
How is this cap built?
It is a black plastic cap with nine vertical towers and female terminals. It is designed to fit the original distributor housing and to keep a secure connection with the rotor and ignition wires.
