Good To Know

Q: Why replace this gasket? A: A worn gasket can let air past the throttle body joint, which may cause rough idle or hesitation, so replacing it during intake work restores a clean seal.

Q: Does this match OEM part 420950792? A: Yes, it cross-references OEM part 420950792, so compare that number against your existing gasket before ordering.

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