Keep spark reaching the right cylinder with the ThunderSpark Distributor Cap 925-1079, an OE-replacement cap that drops into the original distributor housing on the 1994-1995 Toyota Camry, 1992-1996 Toyota Celica, and 1992-1995 Toyota MR2. It directs high-voltage current from the ignition coil, through the rotor and internal terminals, to the correct spark plug so the engine fires in the proper order.
Over time a cap can develop carbon tracking, cracks, or corrosion — signs it may need replacing include misfires, hard starting, and general drivability issues. If a worn or cracked cap is the cause, this unit restores a clean, secure connection to the rotor and ignition wires.
- Exact OE Fit: designed to fit original distributor housings for a secure seal and reliable contact points.
- OE-Replacement Quality: built to meet OE specs for terminal alignment, dielectric strength, and conductive path.
- Directs High-Voltage Spark: routes ignition-coil output to the correct cylinder for the proper firing order.
- Heat-Resistant Materials: constructed with high-dielectric compounds to withstand high voltage, thermal cycling, and engine vibration.
Whether it's part of a tune-up or an ignition repair, replacing a failed cap helps restore proper spark delivery and can support normal fuel efficiency and emissions when a bad cap was the cause.
