Distributor Cap for 1989-1992 Ford Probe & More - ThunderSpark 925-1021

Keep every high-voltage pulse headed to the right cylinder with the ThunderSpark Distributor Cap 925-1021, a direct-fit replacement for the 1989-1992 Ford Probe and 1988-1992 Mazda 626. 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 internal terminals, keeping the firing order on track. Over time a cap can develop carbon tracking, cracking, or corrosion — signs it may need replacing include misfires, hard starting, and drivability issues.

• Heat-Resistant Materials: constructed with high-dielectric compounds to withstand high voltage, thermal cycling, and engine vibration.
• OE Replacement Quality: built to meet OE specs for terminal alignment, dielectric strength, and conductive-path precision.
• Directs High-Voltage Spark: routes ignition coil output to the correct cylinder to support the proper firing order.
• Exact OE Fit: designed to fit the original distributor housing for secure contact with the rotor and ignition wires.

If a cracked, carbon-tracked, or worn cap is the cause of a misfire or hard start, this unit replaces it — whether as part of a tune-up or a broader ignition repair. See the "Vehicles it fits" section to confirm the engine for your vehicle.
