Keep high-voltage spark heading to the right cylinder with the ThunderSpark Distributor Cap 925-1037, an OE-replacement cap for conventional distributor-based ignition systems. It's a direct-fit replacement for the 1986-1989 Nissan D21, 1985-1988 Nissan Maxima, and 1987-1989 Nissan Pathfinder — see the "Vehicles it fits" section for engine-level details. The cap directs current from the ignition coil to the correct spark plug through the rotor and its internal terminals, keeping the firing order intact.
Over time distributor caps can develop carbon tracking, cracking, or corrosion, and if a worn cap is the cause of misfires, hard starting, or rough running, this unit replaces it.
- OE-Replacement Quality: Built to meet OE specs for terminal alignment, dielectric strength, and conductive-path precision.
- Heat-Resistant Materials: Constructed with high-dielectric compounds to withstand high voltage, thermal cycling, and engine vibration.
- Directs High-Voltage Spark: Routes ignition-coil output to the correct cylinder to help maintain the proper firing order.
- Designed for OE Fit: Made to install into the original distributor housing and keep secure contact with the rotor and ignition wires.
