AC Delco Double Platinum Spark Plug 41-962
Description
The ACDelco Double Platinum Spark Plug 41-962 is a GM Original Equipment replacement designed and tested to meet General Motors standards. ACDelco pairs a pure copper core with double platinum pads on both the center and ground electrodes, giving the 41-962 strong fouling resistance and consistent ignition throughout its service life. A one-piece, fired-in suppressor seal bonds three glass types into a gas-tight barrier that guards against compression loss and radio frequency interference. The plug ships with a factory-set 1mm gap, so no manual gapping is needed before installation. Precision specs include a 14mm thread, 16mm hex, heat range 14, and 24.2mm insulator height, all held to the tolerances General Motors requires. Key Features
Features
- Cooler Running Core: Copper construction lowers electrode temperature to resist carbon buildup and fouling
- Consistent Firing Voltage: Platinum on both electrodes maintains stable voltage, reducing ignition coil strain
- Three-Glass Suppressor Seal: Fused one-piece barrier stands up to high compression pressures over time
- Electromagnetic Interference Control: Built-in suppressor protects onboard vehicle electronics from spark-generated noise
- Extended Service Life: Platinum on both firing surfaces reduces wear from repeated spark cycles
- Direct OE Fit: Matches original equipment thread, hex, gap, and heat range specifications
