Good To Know

Q: Should this gasket be replaced every time the throttle body is removed? A: Yes, gaskets are typically single-use, and reinstalling a compressed or torn gasket can cause air leaks. Replacing it during reassembly helps ensure a reliable seal.

Q: Does this gasket fit other 1503 models beyond the Wake 310? A: Fitment depends on the specific model and year, so confirm your machine and part number match 420950792 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.
