Good To Know

Q: Is this an original Sea-Doo part? A: This is an aftermarket intake valve for Sea-Doo, not an original brand component. It is produced to match the fit and function of the OEM part number listed.

Q: How many valves should I replace at once? A: Replacing all intake valves together during a top-end rebuild is common practice. This keeps wear even across the cylinder head and avoids repeat teardown.
