Part# BMK27-EA

Dmaxstore Note: After installing this system on our twin-turbo LBZ we have noticed substantially cleaner oil. In addition to running cleaner, you will gain an extra 2 quarts of oil capacity making this system a must-have for any Duramax.


The Ea By-Pass 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 By-Pass 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.

Higher Efficiency
AMSOIL EaBP Filters have an efficiency of 98.7 percent at two microns. At normal operating RPMs, the EaBP Filter will filter all of the oil in a typical five-quart sump in less than 10 minutes.

Superior Construction
The superior construction of AMSOIL EaBP Filters provides better sealing and increased longevity along with superior corrosion resistance. AMSOIL EaBP Filters have a marine powder-coated exterior, and their zinc-dichromate base plates increase rust protection. EaBP Filters have a nitrile HNBR gasket and an orange silicone anti-drain valve. The two-stage pleated and layered cellulose/full synthetic media has an efficiency rating of 98.7 percent at two microns.

Longer Lasting
When used in conjunction with AMSOIL motor oil and an AMSOIL EaO or Donaldson Endurance™ filter, the EaBP90,
EaBP100, and EaBP110 Filters should be changed every other full-flow filter change up to 60,000 miles or one year whichever comes first. When used with other brands of motor oil or full-flow filters, the EaBP Filter should be changed every other full-flow filter change. AMSOIL recommends using oil analysis when extending oil drain intervals.

AMSOIL recommends changing the EaBP120 every other full-flow filter change up to 90,000 miles or one year whichever comes first. Extended oil drain intervals should always be accompanied by an oil analysis program.

Increased Oil Capacity
The increased fluid system capacity and filtration life provides improved oil cooling and ensures that equipment constantly runs on clean oil. Engine efficiency is increased, providing extended engine life.

Soot Removal
AMSOIL has designed a high-efficiency by-pass filter element that is also a soot removal device. AMSOIL Ea By-Pass Filters use a synthetic/cellulose sandwiched media. The inner layer of the element is composed of highly efficient cellulose media covered with a full synthetic media outer layer. These filters remove 39 percent of soot contaminants less than one micron. Soot removal efficiency increases approximately 10 to 14 percent when the EaBP Filter is used in conjunction with a standard full-flow filter.

By-Pass Filtration Benefits

  • Dramatically Extended Drain Intervals
  • Improved Oil Cooling
  • Increased Filtration Capacity and Life
  • Increased Fluid System Capacity
  • Efficient Small Particle and Soot Removal
  • Significantly Extended Engine Life
  • Equipment Constantly Runs on Clean Oil

Dual Remote Filter System
The AMSOIL Dual Remote Oil Filtration System converts an engine’s full-flow oil filter system into
a full-flow/by-pass oil filtration system by attaching an AMSOIL Full-Flow Oil Filter and AMSOIL
Spin-On By-Pass Oil Filter onto a remote mount. The Dual Remote System provides superior filtration efficiency, increased oil capacity, and improved oil filtration accessibility.

Overall this is a quality kit. The casting and parts used are superb.

The only negative is the mounting bracket supplied doesn't work that well for the limited mounting places. (2016 2500) I had to fabricate my own bracket.
