The SpeedFactory Racing 70mm Thermal Throttle Body Gasket is designed to be used with all common aftermarket cast 68-70mm throttle bodies. Offering precise fitment and a true 70mm bore for maximum airflow. If you want a true bolt-on & go reusable thermal gasket solution that requires no modifications or tedious “aligning” to try and get the gasket to not hang out into the bore, this is your choice.
Providing reduced heat transfer = more power, reduced detonation. Resuable with no difficult and messy mating surface cleanup required.
