Specs At A Glance

Good To Know

Q: Do I need to replace this gasket every time the throttle body comes off? A: Yes, these gaskets are generally single-use, since heat and compression flatten the material and reduce their sealing ability once disturbed.

Q: How do I know the gasket needs replacing? A: Common signs include a rough or hunting idle, lean codes, or visible cracks and flattening on the old 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.
