Specs At A Glance

Good To Know

Q: Does this gasket require any sealant? A: No, this gasket is designed to seal on its own once the throttle body is torqued to specification. Adding sealant is not recommended.

Q: Can I reuse the old gasket? A: A gasket that has been compressed or shows cracking should be replaced to prevent air leaks. Always install a fresh gasket when the throttle body is removed.

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