Heavy-Duty Remote Filtration System and Ea® Bypass Filter combine to provide outstanding oil filtration efficiency
Bypass oil filtration introduces a secondary filter with the purpose of eliminating nearly all contaminants from engine oil. Bypass filters have high capacities and eliminate much smaller particles than full-flow filters, including soot. Bypass filters reduce engine wear through high filtering efficiency, which means they have higher restriction and must be used in conjunction with a full-flow filter.
Bypass filters operate by filtering oil on a "partial-flow" basis. They draw approximately 10 percent of the oil pump's capacity at any one time and trap the extremely small, wear-causing contaminants that full-flow filters can't remove. Bypass filters have a high pressure differential, causing the oil to flow through them very slowly and allowing for the removal of smaller contaminants. It is called bypass filtration because the oil flows from the bypass filter back to the sump and bypasses the engine. This continual process eventually cleans all the oil in the system, reduces long-term wear and can dramatically extend the life of the engine.
AMSOIL Heavy-Duty Bypass System
The AMSOIL Heavy-Duty Bypass System includes the mount, mounting hardware, 15 feet of hose, hose fittings, installation instructions and Bypass Filter (EaBP120). Available separately, the oil sample valve (BK30) eases the process of collecting oil samples. The system provides most of the necessary fittings, except the fitting required to pull pressurized oil from the engine and the return fitting to return oil to the sump. Other parts and fittings can be purchased from any hydraulics or heavy-duty equipment outlet.
High-Quality, Durable Construction
The Heavy-Duty Bypass Filtration System is constructed of high-quality cast aluminum with a steel filter spud that has been thoroughly tested in on-road and severe off-road service. The mount is finished with a thick layer of powder-coated paint to provide maximum resistance to the degrading effects of road salt, debris and engine-compartment chemicals.
General Installation Guidelines
Determine the location of a pressurized oil port on the engine. Pressure ports are usually found on the main oil galley or in close proximity to the full-flow filter head assembly. The oil flow from this source should be plumbed into the inlet side of the filter mount. The outlet will be directed to a low-pressure point on the engine, typically a port located at or near the oil pan. Detailed instructions are included with the Heavy-Duty Bypass Filtration System.
AMSOIL Ea® Heavy-Duty Bypass Filter
The AMSOIL Ea Heavy-Duty Bypass Filter (EaBP120) features a proprietary media that removes 98.7% of all contaminants two microns or larger (ISO 4548-12), and provides superior soot-removal efficiency. It comes complete with a marine powder-coated finish for long filter life, even in extreme conditions.
Increased Oil Capacity
The Ea Heavy-Duty Bypass Filter increases the fluid system capacity by approximately one gallon, depending on length of hose and distance the filter is mounted from the engine. The additional oil and extended filtration life provide improved oil cooling and ensure equipment constantly runs on highly filtered oil. Engine efficiency is increased, providing extended engine life.
Extended Service Life
The Ea Heavy-Duty Bypass Filter offers long service life. Do not exceed the limits listed in the chart below. Extended oil drain intervals should always be accompanied by an oil analysis program.
The Ea Heavy-Duty Bypass Filter was designed for heavy-duty applications. Its robust construction and superior filtration performance provide maximum protection over extended drain intervals, reducing downtime, increasing equipment life and saving money.

Great filterBy  GARY,  a  Verified Buyer  from  Coastal Alabama  on  December 02, 2021Does what its designed to do.Was this review helpful?
EaBP filtersIf there is anything out there that is better, I haven't found it. Even the local fast oil change place see this as mystical. There is no question it keeps my Diesel oil cleaner, longer - period.Was this review helpful?
Ford 6.7L Dual Remote Bypass SystemBy  BIGDADDY KMB,  a  Verified Buyer  from  Lancaster , Ca.  on  October 11, 2021I installed the Bypass system 2 weeks ago and the installation was simple. No Leaks, easy Instructions and Great YouTube installation videos. I ordered additional filters to have on hand. So far So Good. I recommend highly based on research taken for the 6.7.Was this review helpful?
My 2nd install of these kits on my vehicles, worth the moneyBy  MIKE,  a  Verified Buyer  from  Leominster MA   on  September 20, 2021Great productWas this review helpful?
MixedSo originally got the filter with a sinister diesel oil bypass kit. Filter was hard to install and weeped slightly at the gasket. Got it to stop with a little extra torque. After 30k I replaced it as per directions and it was hard to thread on and weeps just a tad. May be the threads on the sinister diesel kit, not sure. But the filter works as intended.Was this review helpful?

Install on a cutaway vanNot to hard to install and the price was the best I found. I have a 2012 Chevy Express 4500 Cutaway with a Duramax. No one makes anything for it. This kit is for a pickup truck. I have a box frame with a fuel operated heater (FOH) right at the only spot this thing can be mounted. I had to fabricate a mount 9” off the frame to hang it. So far it’s not leaked. You can’t upload a pic but its rock solid.Was this review helpful?
Somewhat easy installHardest part is figuring out a mounting location. Also ended up having a different engine sound at the place of the mount. A harmonic sound. Not bad but noticeable.Was this review helpful?
Amsoil dual bypass systemSo 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.Was this review helpful?
20 Years!I have used the the dual filter system since 2001. Love the extended changes and cost savings.Was this review helpful?
