Specs At A Glance

Good To Know

Q: Should this gasket be replaced every time the throttle body is removed? A: Yes, a fresh throttle body gasket is recommended each time the throttle body is taken off, since old gaskets can flatten and leak after compression. Reusing a worn gasket risks vacuum leaks and idle problems.

Q: Does this gasket require sealant? A: It is designed to seal on its own and typically installs dry onto clean, flat mating surfaces. Keep the surfaces free of old gasket material and oil before tightening.

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