Good To Know

Q: What signs point to a bad throttle body gasket? A: Rough idle, lean running codes, or a whistling noise near the intake can indicate a leaking throttle body gasket. A visual check for cracks or flattening confirms it.

Q: Is a new gasket needed every time the throttle body comes off? A: Once compressed, a gasket may not seal reliably again, so replacing it during reassembly is best practice. This gasket matches OEM 420950792.

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