After 6+ years of design, research and development, we are proud to offer this innovative product from our friends at Jbrosg here in Boise, ID. This allows you to run a spin-on oil filter right off of your oil pump on 1985-1999 Evo enginesand is also available for all cone Shovelhead engines. Any engines running the aluminum oil pump will accept this part. This solves the issue that many people have with a custom oil tank application and allows you to filter your oil directly out of the engine before returning to the oil tank, just like the stock setup that have a remote oil filter. For clearance and fitment, see below.
Benefits: This adapter allows you to filter your oil, plain and simple. If you're familiar with building custom Harley's you know it's an eyesore to run an external oil filter somewhere on your frame, and for many people out there, the oil filter just gets eliminated. Don't do that to your engine! Filter that oil and save yourself a major headache. This can also be run in line with the stock oil filter in the oil tank or external oil filters, as a backup oil filter. Keep your oil clean and free of sludge, debris and metal. All of those things cause unnecessary wear on your engine and will wear it out much quicker, but also allow for the potential of catastrophic damage if you're unaware of metal floating around in your oil on a long ride, etc.
Fitment:You will need 4 inches between your oil pump body and your transmission for this to fit with just enough clearance to fit your spin on oil filter in to install it.
