Good To Know

Q: Should I replace this gasket every time I remove the throttle body? A: Yes, gaskets compress over time and reusing one can cause an air leak. A fresh gasket helps ensure a reliable seal.

Q: Does this fit both 2017 and 2019 GTR models listed? A: It is listed for the GTR X 230 1503 and GTR STD HO 1503 models shown. Confirm your serial number and engine 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.
