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. |

(Typical Instal for BMK11
and BMK12 Kits) |
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
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.

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
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, 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.

NOTES:
1. Special adapters and hardware may
be required for some installations.
A universal mounting bracket is
included with the kit, however,
custom brackets may be required
depending on your vehicle's
equipment options or personal
preferences in mounting locations."
