NGK Spark Plug R5673-9
Built for boost, bottle, or balls-out RPM. The NGK R5673-9 is a no-resistor, cold-range, race-grade plug made for engines that live in the red. Short reach, tight tolerance, and zero forgiveness—just the way you like it.
This ain’t for grocery-getters. It’s for high-compression hitters and track-day terrorizers. Add to cart and keep the fire lit where it matters most.
