NGK Laser Platinum Spark Plug (PTR5A-13)

The dual platinum surfaces on these NGK Laser Platinum spark plugs are laser-welded, which helps them wear down slowly. This design is a key reason they offer a longer service life compared to standard nickel spark plugs, meaning you won't be changing them as often. They're built to OE specifications, so you can expect them to fit right and perform as the original equipment did.

Inside, a pure alumina silicate ceramic insulator handles heat transfer well and provides solid strength, while the trivalent metal plating on the outside helps prevent corrosion and makes them easier to remove later. The copper core is there to help dissipate heat, keeping the plug from overheating, and the corrugated ribs on the insulator help prevent flashover. These are a great choice for vehicles that originally came with fine wire platinum alloy plugs, offering stable idling and improved fuel efficiency.

This set comes with four spark plugs, which is what most 4-cylinder engines need. If your vehicle uses more or fewer cylinders, you'll want to adjust your order accordingly. They are designed to fit a wide range of vehicles, including many Ford, Chevrolet, and Mazda models.
