Good To Know

Q: Does this gasket fit both the 130 and 155 versions of the 1503 engines used in the GTI? A: The gasket follows the throttle body and intake joint rather than the engine output rating, and it is listed here for the GTI P LTD 155 1503 in 2018. Confirm your model and year before ordering.

Q: What are signs the throttle body gasket needs replacement? A: Rough idle, whistling at the intake, and lean-running codes can point to a failed gasket at this junction. A smoke test helps confirm the leak location before parts are ordered.

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