Send a clean, correctly-timed spark to the right cylinder with the ThunderSpark Distributor Cap 925-1013 (also written 9251013), an OE-replacement cap for conventional distributor-based ignition systems. It's a direct-fit replacement for a wide range of 1990s–2000 GM trucks and SUVs, including the 1999-2000 Cadillac Escalade, 1996-1999 Chevrolet C1500, 1996-2000 Chevrolet Tahoe, 1996-2000 GMC Yukon and 1999-2000 GMC Sierra 1500 — see the Buyer's Guide tab for the full list of 51 applications.
The distributor cap routes high-voltage current from the ignition coil to the appropriate spark plug through the rotor and internal terminals, keeping the firing order intact. Over time caps can develop carbon tracking, cracks or corrosion, which may show up as misfires, hard starting and rough running.
- Directs high-voltage spark: routes ignition-coil output to the correct cylinder to maintain proper firing order.
- OE-replacement quality: built to meet OE specs for terminal alignment, dielectric strength and conductive-path precision.
- Heat-resistant materials: high-dielectric compounds designed to withstand high voltage, thermal cycling and engine vibration.
- Designed for OE fit: installs into the original distributor housing for a secure connection with the rotor and ignition wires.
If a cracked or worn cap is the cause of your misfire or hard start, replacing it helps restore consistent spark delivery.
