Good To Know

Q: Will this adapter work with my factory throttle body? A: It is designed to mount a 3 bolt throttle body to a 4 bolt intake, so confirm your throttle body bolt pattern matches before ordering.

Q: Do I need a gasket with this adapter? A: A gasket or sealant is typically used on both mating surfaces to prevent vacuum leaks, and these are usually sold separately.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
