Specs At A Glance

Good To Know

Q: Should this gasket be replaced every time the throttle body is removed? A: Yes, gaskets compress and harden over time, so replacing it each time the throttle body is removed helps prevent vacuum leaks. Reusing an old gasket risks an improper seal.

Q: Does this gasket require any sealant during installation? A: No, this style of gasket is designed to seal on its own once the throttle body is torqued to spec. Adding sealant can interfere with proper seating.

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