Good To Know

Q: Can a bad throttle body gasket affect engine performance? A: Yes, a leaking gasket lets unmetered air into the intake, which can cause rough idling, lean running, or hesitation. Replacing it restores a proper seal.

Q: Should this gasket be reused after removing the throttle body? A: Gaskets of this type are typically single-use and should be replaced any time the throttle body is removed. Reusing a compressed gasket risks vacuum leaks.

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