Kohler Oil Filter Cross Reference to Fram
Maintaining your Kohler small engine is essential for keeping your lawn mower, tractor, or outdoor power equipment running smoothly. When it is time for a routine oil change, finding the exact OEM part number can sometimes slow you down. Fortunately, understanding a reliable Kohler oil filter cross reference to Fram makes selecting the correct aftermarket replacement quick and stress-free.
Whether you own a Kohler Courage, Command, or a heavy-duty commercial V-twin engine, Fram manufactures a compatible filter that meets or exceeds original equipment specifications. This guide outlines the most common Kohler part numbers and pairs them directly with their Fram equivalents.
Understanding Kohler Engine Oil Filters
Kohler uses several different oil filters depending on the engine's horsepower, cylinder configuration, and physical space constraints under the hood. Most modern Kohler engines utilize spin-on filters equipped with specific internal bypass valve pressures and anti-drainback valves.
Using the wrong filter can lead to improper oil pressure, oil starvation upon startup, or even leaks if the thread pitch and gasket diameter do not match precisely. That is why relying on an accurate cross reference is crucial before heading to the auto parts store.

4. Short Filters for Tight Spaces: Kohler 24 050 13-S
Certain zero-turn mowers and specialized tractor frames feature very tight installation clearances where a standard-length filter will hit the frame or exhaust components.
- OEM Part Numbers: 24 050 13-S, 24 050 08-S
- Fram Cross Reference: Fram PH4967
- Application Notes: The PH4967 is a shorter profile filter that provides the necessary clearance while maintaining correct internal bypass parameters.
Tips for Changing Your Kohler Oil Filter
Once you have used a cross reference guide to purchase your Fram filter, follow these best practices to ensure a clean, leak-free installation:
- Warm up the engine: Run the engine for 3 to 5 minutes to warm the oil, allowing it to drain more thoroughly and carry away suspended contaminants.
- Lubricate the gasket: Dip a clean finger in fresh engine oil and smear a light film over the rubber gasket of the new Fram filter. This ensures a proper seal and prevents the gasket from sticking during the next oil change.
- Hand-tighten only: Spin the new filter on until the rubber gasket makes firm contact with the mounting pad. From that point, turn it an additional 3/4 to 1 full turn by hand. Never use a wrench to tighten an oil filter, as overtightening can crush the gasket or ruin the mounting threads.
- Check for leaks: Refill the engine with the recommended amount and viscosity of oil, start the equipment, and check around the filter base for any signs of leaking.
Final Thoughts
Finding an aftermarket replacement doesn't have to be a guessing game. By keeping this Kohler oil filter cross reference handy, you can easily select the appropriate Fram filter, protect your small engine from premature wear, and get back to maintaining your property with confidence.
