Superior small-particle filtration, including soot removal
Increased filtration capacity and life
Equipment constantly runs on clean oil
Helps increase engine efficiency and life
Helps reduce maintenance costs
System includes mount, mounting hardware, hose and hose fittings. Note: The spin-on adapter, EaO26 full-flow oil filter, and a Bypass oil filter are each sold separately. EaBP120 will not work with this system. You must purchase the spin-on adapter that matches the filter thread size on your vehicle (see table on Detail Page)
The Bypass Oil Filter (EaBP) provides the best possible filtration protection against wear and oil degradation. Working in conjunction with the engine's full-flow oil filter, the AMSOIL Ea Bypass Filter operates by filtering oil on a "partial-flow" basis. It draws approximately 10 percent of the oil pump's capacity at any one time and traps the extremely small, wear-causing contaminants that full-flow filters can't remove. The AMSOIL Ea Bypass Filter typically filters all the oil in the system several times an hour, so the engine continuously receives analytically clean oil.

*If you Don't see your AMSOIL Filter in this thread adapters table, please use the BMK21 Bypass System instead.
My 2003 Dixie Chopper lawn mower came with a BP90 Amsoil bypass filter. The mower is 21 years old and runs as good as when it was new. I feel like the bypass filter has saved me a lot of money in not having to by a new motor or mower because of a worn motor!
I have had the Dual Filter system on 3 GMC Pickups that towed my 10,000 pound Airstream all over all the Lower 48, most of the Canadian Provences, two summers in Alaska, and two summers in Newfoundland.
For several years I always sent oil off for testing when I changed the oil at the end of the year, and never got a report stating I needed to change the oil.
I no longer send oil off for testing, and have never had a problem.
I Chang the full floe filter twice per year, and the Bypass filter once per year, and always use the top quality Amsoil at the time.
My last two trucks have been DuraMax Diesels, one of them now owned by a friend now has over 200,000 miles on it, and still pulls his travel trailer all over. It still follows my oil change program, I supply the oil and filters for the truck.
What a difference this has made in the oil quality. 2 microns vs. 20 microns of filtration makes a huge difference. With the cost of oil and filters today this will allow me to extend my change intervals. I should have the return on the investment in 2 oil changes, not to mention the overall protection of my engine.
Bottom Line
Yes, I would recommend this to a friend.

Great kit, simple install, definitely recommend for anyone wanting to get more life out of their oil and truck.
Put a super charger on my car and just thought the best oil for my engine would be a good idea.
Tried it on a whim and the install only took a few hours.
Was concerned about introducing leaks to the oil system but the unit is so stout and of such high quality, there are no issues at all.
Just make sure you order the right adapter and right filters for that set up. I was sure I had it right from the chart but after I emailed Amsoil they clarified the correct adapter.
You do not use the normal cars oil filter anymore. You use larger and better filters that fit the bypass system.
You oil is being constantly cleaned by the low micron bypass filter, really good.
I would recommend getting the sample tap off valve just so you can easily check the oil.
Time to change the oil, let be check, WOW completely golden brand new looking oil when I pull if off the tap.
Just really nice to see how well the system is. When I do decide to change the oil, that still golden oil is great for all my yard machines; Lawn mower, compressor, edger, snow blower, etc.
I had the oil tested and they asked why I was testing new oil. No breakdown of the oil at all.
If you want to protect your engine and keep your expensive synthetic oil clean this is the way to go.
The oil does not really breakdown, it just gets dirty with the abrasive carbon blow by.
If you are thinking about a bypass filter this is the way to go.
So if you have a 6.0 you know all its issues. This filter aids in keeping the oil cooler passages cleaner and helps the needed clean oil for running the fuel injectors. Great product. Thx.
Bottom Line
Yes, I would recommend this to a friend.
