EaAB Crankcase Breather
Filters provide excellent oil vapor control, increased efficiency
and superior engine performance in street rod and racing applications.
EaAB Filters are a perfect complement to EaAR Filters, ensuring
superior air filtration in high-performance and severe-service
Why Are Crankcase Breathers Necessary?
Pressure builds in the engine crankcase due to
vapor from hot engine oil and from exhaust gases that escape past
the piston rings. A crankcase breather system is used to release
this pressure. If the breather system becomes blocked, the crankcase
pressure builds internally. As the pressure increases, the oil
is pushed through the area offering the least resistance, such
as the dipstick or a seal. Crankcase breather filters are employed
to ensure the crankcase does not become blocked with foreign materials
as pressurized gases escape.
AMSOIL EaAB Filters
AMSOIL EaAB Filters are compatible with engines,
transmissions and oil tanks, but are mainly designed for installation
on valve covers used in high-performance and racing applications.
EaAB Filters clamp directly to rubber tubing or are pushed onto
rubber grommets. The EaAB-1511, EaAB-1513 and EaAB-1514 feature
a chrome shield for added protection from direct contact with
dirt and grime, and all EaAB Filters feature a chrome ring with
AMSOIL engraved into the top. The EaAB-1491 is a push-in filter
and the others are all clamp-on designs.
AMSOIL EaAB Filters are made with the same super
high-quality synthetic nanofibers used in other Ea Filters. Their
wire-backed pleats provide additional strength and filter longevity.
The signature AMSOIL Ea blue media, along with the chrome detailing,
make these filters an attractive fit.
AMSOIL EaAB Filters are cleanable, offering longer
filter life. They are cleaned in the same manner as other Ea Air
Filters: using either low-pressure shop air on the clean side
or a vacuum on the dirty side.
AMSOIL EaAB Filters are available for any vehicle
or piece of equipment that can accept breather elements. The breathers
are designed for installation on engine valve covers and other
breather tubes, but can also be used on transmissions and industrial
equipment. See the product dimension chart below for appropriate
