Restore Your Engine’s Factory Performance

Don't settle for "universal" fitments. The ACDelco 41-962 Double Platinum Spark Plug is the GM Original Equipment (OE) replacement designed specifically for your Chevrolet, GMC, or Cadillac vehicle.1 Engineered to meet the exact specifications of your engine, these plugs ensure a smooth idle, maximum fuel economy, and reliable cold starts.

Why Choose Double Platinum?

Unlike standard copper or single-platinum plugs, the 41-962 features platinum pads on both the center and ground electrodes.

  • 100,000-Mile Service Life: Superior resistance to spark erosion and fouling means you won't have to worry about a replacement for years.

  • Better Fuel Economy: A consistent, precise spark ensures complete combustion, squeezing every bit of power out of your fuel.2

  • Reduced Ignition Stress: Designed to require lower voltage to fire, protecting your ignition coils from premature wear.3


  • Corrosion Protection: The nickel-plated shell prevents seizing in the cylinder head, making future removals easy.

Key Technical Features

    • Fired-In Suppressor Seal: Blocks radio frequency interference (RFI) that can affect your vehicle’s electronics and ensures a gas-tight seal.4

    • Copper Core: Provides excellent heat transfer to help prevent pre-ignition and "knocking."5

    • Precision Pre-Gapped: Factory-set at 0.040" for a quick, drop-in installation.

Quick Tips for Installation

    1. Check Gap: While pre-gapped at 0.040", always double-check the gap gently to ensure it wasn't bumped during shipping.

    2. Hand Thread First: Always start the threads by hand to prevent cross-threading the cylinder head.

    3. No Anti-Seize: ACDelco shells are plated and generally do not require anti-seize (which can affect torque readings).
