Specs At A Glance

Good To Know

Q: Is this an original Sea-Doo part? A: This is an aftermarket intake manifold O-ring built to cross-reference 420431662, and it is not an original Sea-Doo product. Confirm the number on your old seal before ordering.

Q: Should the O-ring be replaced every time the manifold comes off? A: Yes, intake seals are one-time-use in most cases and should be swapped whenever the manifold is separated. Reusing a compressed ring risks an air leak.

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