NGK Spark Plug R5674-7 crosses to AR12
Crosses to AR12 and plays nice with compression, heat, and high-RPM punishment. The NGK R5674-7 is a non-resistor, projected tip plug with a colder heat range for engines that like to work hard and stay cool.
Perfect for nitrous, boost, or big cam builds that live above 5,000 RPM. Gap it tight, send it wide. Add to cart and let it rip.
