Running the wrong main jet size kills performance and creates drivability issues—lean stumbling, flat spots, or overly rich running that wastes fuel and fouls plugs.

Whether you're rejetting after modifications or replacing a worn jet, this 4-pack gives you spares for future tuning.

Helps keep cool, works great!

Bought the dual pass Allstar radiator for my build, and it’s been solid. Keeps the engine running cool even on the hottest days no complaints here!
