Specs At A Glance

Good To Know

Q: Should this gasket be replaced every time the throttle body is removed? A: Yes, gaskets are typically single-use and should be replaced whenever the throttle body is unbolted to ensure a proper seal.

Q: Does this gasket require sealant during installation? A: No, it is designed to seal on its own when torqued to specification, so additional sealant is not needed.

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