Good To Know

Q: Does this gasket fit the 2017 GTXS STD 155? A: Yes, it is listed for that 2017 model with the 155 HP 1503 engine. Confirm your engine and serial number before ordering.

Q: Should the gasket be replaced every time the throttle body is removed? A: Gaskets are typically single use, so a fresh one is recommended on reassembly. This helps avoid air leaks at the mounting surface.

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