Specs At A Glance

Good To Know

Q: Do I need to replace the O-rings every time? A: Replacing the O-rings along with the filter is good practice, since aged seals are a common source of slow oil seepage on the 1630 engine.

Q: Is this kit a complete oil change package? A: It covers the filter element and sealing O-rings, so engine oil must be purchased separately.

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