PRODUCT DESCRIPTION
The AMSOIL By-Pass Oil Filter provides the best
possible filtration protection against wear, oil
degradation, rust and corrosion. Working in
conjunction with the engine’s full-flow oil filter,
the AMSOIL 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 and water that full-flow filters can’t
remove. The AMSOIL By-Pass Filter typically filters
all the oil in the system several times an hour, so
the engine continuously receives analytically clean
oil. More info on the
AMSOIL EaBP By-Pass Filter Elements

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

AMSOIL
offers by-pass components 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 new Aluminum
Billet Oil Filter Cap (BK1101), the Aluminum
Billet Oil Fill Cap (BK1102) and the
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
(BP241), the Aluminum Billet Oil Fill Cap
for Dodge 5.9L Cummins diesels (BK1301), for
6.7L Cummins engines use (BK1302), and the
90-degree JIC Elbow (BP242) (all sold
separately). The BP241 fits onto the
existing plug on top of the OEM full-flow
filter mount, and the addition of the BK1301
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:
1.
Aluminum oil filter Sandwich Adapter
with o-ring (BK1201)
2. Aluminum Billet Oil Filler Cap for GM
Duramax (BK1202)
3. Two 90 degree JIC Elbows (BP242)
4. Single Remote By-pass system (BMK21)
5. By-pass filter (EaBP90, EaBP100, or
EaBP110, as space dictates)

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 By-Pass Filter Elements
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 Oil Filter
or
Donaldson Endurance™
OilFilter, the EaBP should be changed every other full-flow filter
change up to 60,000 miles. 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.
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 a 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
• Increased Engine Efficiency
• Remove Particles Less Than One Micron
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. See the
G1092
brochure for more info on the Dual Remote Filtration
System.

Normal Service Life b:When
used in conjunction with AMSOIL motor
oil and an EaO or Donaldson Endurance
filter, EaBP Filters should be changed
every other full flow filter change up
to 60,000 miles. 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.

a. Filters can
be used on sumps of larger capacity but then require
more frequent replacement. Full details on service
life included with filter installation instructions.

Data determined in a non-turbo gasoline engine with
AMSOIL 100% Synthetic Motor Oil and AMSOIL Full-Flow
Oil Filter. Service life varies in other engines
(turbo and diesel) and with other oils and filters.
