What makes these NGK Laser Platinum spark plugs different from standard plugs?

These plugs feature a dual platinum surface that is laser-welded, which significantly slows down wear compared to conventional nickel plugs. This design helps maintain consistent performance and extends the plug's service life.

What does the copper core in the spark plug do?

The copper core is essential for heat management. It helps to draw excess heat away from the spark plug's firing tip, preventing it from overheating and ensuring reliable operation.

Are these spark plugs sold individually or as a set?

This listing is for a box of four NGK Laser Platinum spark plugs (PFR7AB). If your vehicle requires a different number of spark plugs, you would need to order the appropriate quantity.

Product Details

You get a box of four NGK Laser Platinum spark plugs, part number PFR7AB, designed to keep your snowmobile running strong. These aren't your average spark plugs; they feature a dual platinum surface that's laser-welded, which means they wear down much slower than standard nickel plugs. This slow wear rate helps maintain stable idling, improves fuel efficiency, and can even lower emissions over time.

The construction here is solid. You'll find a pure alumina silicate ceramic insulator that's really strong and transfers heat well, preventing the plug from getting too hot. Plus, the copper core helps pull away excess heat, and the trivalent metal plating on the outside makes them resistant to corrosion and seizing, which is a big help when it comes to getting them in and out. These are a great choice if your snowmobile originally came with fine wire platinum alloy plugs.

This set fits a wide range of Ski-Doo snowmobiles, including models like the Expedition Xtreme E-TEC 800R, MX Z TNT E-TEC 800R, and Summit SP E-TEC 800R. Make sure to check the fitment details to confirm compatibility with your specific machine.
