AMSOIL Absolute Efficiency Ea Bypass Oil Filters

Working in conjunction with the engine’s full-flow oil filter, AMSOIL Ea By-Pass 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. The AMSOIL Ea By-Pass Filter typically filters all the oil in the system several times an hour, so the engine continuously receives analytically clean oil.

New Aluminum Billet Oil Fill and Oil Filter Caps for BMK21 By-Pass Filtration SystemBillet Caps

AMSOIL offers by-pass components (sold separately) to ease the installation of the BMK21 By-Pass Filtration System in three popular diesel engines: the Ford 6.0L Power Stroke™, the Dodge 5.9L Cummins and the General Motors 6.6L Duramax.

Engine compartments are becoming increasingly cramped, leaving little room for after-market additions and improvements. The BMK21 is a single remote by-pass filter system that fits into much smaller spaces than the AMSOIL Dual-Remote By-Pass System.

Ford 6.0L/6.4L Power Stroke™ Diesels
To ease installation of the BMK21 on 2003 and later model Ford pickups equipped with the 6.0L and 6.4L Power Stroke™ diesel engines, AMSOIL offers the:

  • Aluminum Billet Oil Filter Cap (BK1101),
  • Aluminum Billet Oil Fill Cap (BK1102) and
  • 90-degree JIC Elbow (BP242, two recommended) (all sold separately).

These new high-quality billet aluminum caps replace the original equipment manufacturer (OEM) filter cap and oil fill cap. The new caps have holes tapped in them that accept the JIC elbows for hose connectors.

Dodge 5.9L/6.7L Cummins Diesels
To ease installation of the BMK21 in later model Dodge pickups equipped with the 5.9L and 6.7L Cummins diesel engine, AMSOIL offers the:

  • 1/8" NPT - 1/4" JIC fitting (BP242),
  • Aluminum Billet Oil Fill Cap for Dodge 5.9L Cummins diesels (BK1301) for 2007 & Older

For 6.7L Cummins engines use:

  • (BK1302) Aluminum Billet Oil Fill Cap for 2008 & Newer
  • 90-degree JIC Elbow (BP242) (all sold separately).

The BP242 fits onto the existing plug on top of the OEM full-flow filter mount, and the addition of the BK1301/BK1302 eases the installation of the oil return line.

General Motors 6.6L Duramax Diesels
To provide GM Duramax owners the same ease of installing the BMK21, AMSOIL is now offering an oil filter “Sandwich” adapter (BK1201).

The Sandwich adapter is an anodized billet aluminum adapter that screws on to the present full flow oil filter nipple located on the engine block. The full flow filter is then simply spun on to the adapter. The Sandwich adapter has an orifice to provide high-pressure oil feed for the BMK21. Like the other diesel applications, AMSOIL now offers an Aluminum Billet Oil Filler Cap for (BK1202) to ease the installation of the oil flow from the BMK11 back to the engine. To complete an installation, the following components must be purchased separately:

  • Aluminum oil filter Sandwich Adapter with o-ring (BK1201)
  • Aluminum Billet Oil Filler Cap for GM Duramax (BK1202)
  • Two 90 degree JIC Elbows (BP242)
  • Single Remote By-pass system (BMK21)
  • By-pass filter (EaBP90, EaBP100, or EaBP110, as space dictates) (all sold separately)
