Each kit easily mounts on tubular engine mounts or the engine firewall, depending on your application. Once mounted, the oil filter base connects in-line between the engine scavenge oil pump outlet and the oil cooler (or oil tank if no cooler) to help keep particles from the engine out of your oil cooler and tank. Oil pressure screens are not removed during the installation and only need to be inspected annually.

Airwolf currently offers 4 system variations to provide filtration for a wide range of engine sizes from small to very large, multibank radial engines. The single filter oil filter bases are specifically designed for scavenge oil line sizes that range from -12 (0.75”) up to -20 (1.25”) and our twin-filter “Super Gorilla” base is designed for the flow of -24 (1.50”) scavenge oil lines.

Select Remote Oil Filter Kit by reviewing Airwolf’s application chart and corresponding installation manual.

*Confirm your desired mount location and scavenge lines on your aircraft prior to ordering. Engine mount tube size and/or fitting type may vary from our standardized kit contents and must be provided when ordering. This applies only to kits that mount on engine mount tubes.
Hoses & Clamps not included unless where indicated.

Benefits of Airwolf Remote FAA/ PMA Oil Filter Kits:

• Keeps your oil clean!
• Extends engine life.
• Radial engine aircraft came equipped with and still only have an oil screen.
• Oil screens do nothing to protect your engine. An oil screen’s sole purpose is to catch particles when the engine starts making metal. Particles larger than 20 microns (.001”) will cause damage.
• Oil filters will trap tiny particles which can be found during filter element inspections, so you know you have a problem before it’s too late.
• Filters oil before the oil cooler, keeping any particles in the engine from ruining the oil cooler.
• Oil changes take minutes, not hours. Ends messy oil changes!
• *Kits do not include hoses unless where indicated.
