Ford 7.3L Dual-Remote Oil Bypass System
Whate are the Benefits of Oil Bypass Systems?
Efficient Small Particle and Soot Removal
The high-efficiency AMSOIL Ea® Bypass Filter element is also an effective soot-removal device. The filter element is composed of a highly efficient media, which increases soot-removal efficiency when the bypass filter is used in conjunction with a standard full-flow filter.
Significantly Extended Engine Life
The majority of engine wear is caused by particles in the 5-20 micron range. Because AMSOIL Ea® Bypass Filters effectively remove contaminants down to 2 microns, your engine receives the ultimate in wear protection. Less engine wear keeps the engine in better physical condition, extending its life.
Increased Filtration Capacity and Life
An additional filter adds additional opportunity to filter particles out of the oil. The full-flow filter removes larger particles down to about 20 microns, while the bypass filter removes the smaller particles down to 2 microns. Working together, these filters provide next-level protection for your engine.
Improved Oil Cooling
With increased oil capacity, the oil filtration system contains more fluid through which it can disperse heat from the engine. This allows the engine and the oil to run cooler.
Increased Fluid System Capacity
By installing an additional filter, the engine oiling system has the capacity to hold more oil. The increased fluid capacity and filtration life ensures the equipment constantly runs on highly filtered oil. Engine efficiency is increased, providing extended engine life.
Reduced Maintenance Costs
AMSOIL Bypass Systems provide a dramatic increase in engine protection. Proven to help you avoid costly repairs associated with engine wear.
Dramatically Extended Drain Intervals
AMSOIL Ea® Bypass Filters can help users extend their oil drain intervals. AMSOIL recommends using oil analysis when extending oil drain intervals.

Great filters
Hard to find these filters anywhere else. And decent price I bought them for my secondary oil filter on my 2008 f350 and they fit the sinister diesel kit.

Expensive, but if it does what it claims
I'm kind of up in the air on this one. Installed the BMK 28 Dual remote bypass filter system on my 2017 F350 Power Stroke to try to protect my investment. The system was very expensive, but it is supposed to keep my oil much cleaner. After checking my oil after several hundred miles, it did appear cleaner than the stock filter would have done. After several hundred more miles, it was as black as it was before changing it. This is not an old truck with several hundred thousand miles on it, it has just 21,000 on the clock. The replacement filters are twice the price as most other brands, and from my observations don't seem to be making that much more of a difference. They are also the only filters that will fit on Amsoils filter systems, with no other options available due to their filter bung size. Time will tell.

Does a great job
The filter does a good job allowing me to do extended drain intervals. I sample every 25,000 miles and determine my oil changes from the results. I do wish they made a shorter version as I have limited space.

Amsoil dual bypass system
So far I am pleased with the function and ease of install. Still to early to see how effective this product will be. Will do oil sampling to monitor oil quality. Have high hopes, time will tell.
