NGK Laser Platinum Spark Plug Box of 4 (PZTR5A-15)

These NGK Laser Platinum spark plugs are a direct OE replacement, meaning they're built to the same standards as the plugs your vehicle came with from the factory. They fit a wide variety of vehicles, including many Buick, Chevrolet, and GMC models from the 90s and early 2000s. If your vehicle originally came with fine wire platinum alloy plugs, these are a solid choice to get your engine running smoothly again.

What sets these apart is the dual platinum construction. A platinum pad on the ground electrode, combined with a platinum tip on the center electrode, helps them wear slowly and evenly, especially in modern distributorless ignition systems. This slow wear rate contributes to stable idling, better fuel economy, and lower emissions over their service life. The pure alumina ceramic insulator is strong and transfers heat well, while the copper core inside helps prevent the plug from overheating. Plus, the trivalent metal plating on the threads helps prevent corrosion and makes them easier to remove down the road.

You get a box of four plugs, which is the correct amount for most 4-cylinder engines. Just remember to check your vehicle's specific needs to ensure you're getting the right quantity and type of spark plug.
