NGK Single Platinum Spark Plug Box of 4 (BUR9EQP)

If you're working on your 1984-1995 Mazda RX-7, these NGK single platinum spark plugs are a solid choice for keeping that rotary engine running smoothly. They're built to be a direct OE replacement, meaning they're designed to fit right and perform as expected straight out of the box.

These plugs use a platinum pad on the ground electrode, which helps them wear more evenly, especially in distributorless ignition systems common on these cars. The pure alumina silicate ceramic insulator is strong and transfers heat well, while the trivalent metal plating helps prevent corrosion and makes them easier to remove down the road. Plus, the copper core inside helps pull heat away from the firing tip, which is important for preventing overheating and ensuring reliable starts, especially with rotary engines.

This set comes with four plugs, which is exactly what you'll need for your RX-7. Just remember to check your service manual for the correct gap setting before installation.
