NGK 5820 Crosses to AR2592

Crosses to AR2592 and built to play rough. The NGK 5820 is a race-bred, non-resistor plug for when your ignition system doesn’t have time for interference—or failure. Short thread, projected tip, and a heat range made for high-compression, high-RPM nonsense.

This is what you run when you’re not messing around. Add to cart and let the sparks fly—literally.

"LOVE these plugs, cold heat range for high boost application." -Paul Ferry
