Good To Know

Q: Do I need to replace the intake manifold O-ring every time I remove the manifold? A: Yes, it is good practice to fit a fresh O-ring whenever the manifold is removed, since a used ring may not reseal reliably. Q: Is this an original Sea-Doo part? A: This is a replacement intake manifold O-ring cross-referenced to OEM part number 420431662, not an original brand part.

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