ThunderSpark Distributor Cap P/N:925-1007
Keep high-voltage spark flowing to the right cylinder with the ThunderSpark Distributor Cap 925-1033, an OE-replacement cap for conventional distributor-based ignition systems. It drops in as a direct-fit replacement for the 1988-1989 Ford Festiva, 1989 Mazda B2600, and 1989-1990 Mazda MPV — see the "Vehicles it fits" section for the full engine breakdown. The cap directs current from the ignition coil to the appropriate spark plug via the rotor and internal terminals, and over time caps can suffer carbon tracking, cracking, or corrosion that leads to misfires, hard starting, and drivability issues.
If a cracked or worn cap is the cause of misfires or hard starts, replacing it helps restore consistent spark delivery — a smart step during a tune-up or ignition system repair.
