EMPI Remote Oil Filter Relocation Mount Left Side 3/8 NPT for Harley-Davidson Evo and Twin Cam
Relocating the oil filter to a custom position cleans up the engine bay, simplifies oil changes on tight builds, and eliminates the mess that the stock filter location creates when draining. This cast aluminum adapter replaces the standard oil filter housing and accepts standard spin-on filters, giving builders a clean starting point for any custom filter routing on Harley-Davidson Evolution and Twin Cam engines.
Key Features
- Remote bypass adapter that replaces the bolt-on oil filter housing or spin-on oil filter, allowing the filter to be relocated to any position on the build
- Left-side port orientation – both oil line ports exit on the left side of the mount for routing oil lines to the filter in that direction
- 3/8 NPT female port threads on both inlet and outlet for standard oil line fittings
- 3/4-16 threaded nipple accepts standard spin-on oil filters including HD #1156 and Fram PH8A
- Cast aluminum housing – durable, lightweight, corrosion-resistant for exposed drivetrain environments
- Available in Uncoated (natural aluminum) and Black powder coat for finish matching to the build
