Why Replace the Oil Filter and Spark Plug Together
The oil filter and the spark plug do different jobs in your generator engine, and both are part of regular service. Replacing them in the same session can make maintenance easier to plan, because you only need to prepare for one service visit instead of two.
UGP Oil Filter Replacing Onan 0122-0836
The UGP oil filter helps remove contaminants from the engine’s lubrication system. It replaces Onan 0122-0836 and is intended for use during routine oil service. Keeping the lubrication system clean is a basic part of caring for any engine, and an RV generator is no exception.
UGP Spark Plug Replacing Onan 0167-1638
The UGP spark plug supports reliable ignition and consistent operation. It replaces Onan 0167-1638 and is intended for routine spark plug replacement. Ignition parts wear over time, so replacing the plug as part of scheduled maintenance is a common practice among generator owners.
Because the Onan 0122-0836 oil filter and spark plug kit includes both parts, you can gather what you need in a single order. Always follow the service interval listed in your generator owner’s manual.
Check Compatibility Before You Order
Choose the right parts the first time by confirming the following details for your generator:
- Generator model

- Required part numbers
Compare these details with the compatibility information on this page. If they do not match, do not order this kit, and look for the correct parts for your generator instead.
