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 productsAmsoil is definitely one of the best products on the market. Amsoil if the only lubricant I use in all of my equipment.
Great filtersHard 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
Does a great jobThe 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.
Get all the impurities outCan't find a better solution to fine particle filtration and I recommend this to all my friends as the best protection money can buy for your mega expensive high-end diesel engine...
EABP100Excellent product, it filters unwanted residue.
It WorksFairly easy install using mounting brackets I purchased from Don's oil (youtube). I have 1000 miles on the oil and it looks a lot cleaner so it's doing it's job. It increased my oil capacity by 3 qts.I wish they would use a standard Ford 6.7 mount though for the primary filter.
Universal Single-Remote Bypass SystemBy  TERRANCE,  a  Verified Buyer  from  Index, Washington  on  May 22, 2021This system is still in it’s infancy as to my assessing of it’s performance, but it is DEFINITELY a more user friendly, higher quality, less expensive, and easier to order system than my previous Bypass System. I’ve been using Amsoil products for nearly 20 years and I have NEVER been disappointed by their quality and support. If their past is any indicator, I’m sure this Bypass System will exceed my expectations greatly.
Great filterThis installed on my 97 7.3 and keeps my oil from getting too thick with soot. works great.
bypass filtebypass filter came on the dixie chopper mower. just replaced it with a new one.
Looks great, haven't installed yetMachine work and finish looks really good. Have not installed yet. So unknown on performance.
