| After
reading the debates about oil filter problems on the various
message boards over the years, we are now offering these
"lifetime" oil filters. No more worries about
inferior anti-drainback valves, paper elements failing or
housings blowing out. Are they expensive?
Yes! Are they worth it?
YES!
Machined aluminum housings
replace stock spin-on filters and accepts a proprietary high
flow synthetic oil filter element. Designed to withstand the
highest pressure surges and rough duty service.
The blue anodized housings
have a removable bottom threaded cap. Element replacement is
done through the bottom cover which is threaded into the body.
These spin-on oil filters
are
offered in several different combinations of mounting thread
and sealing gaskets, along with two lengths to fit most engine
applications. Each housing comes complete with all the
necessary O-rings and gaskets required, and one 8 micron
element.

These filters
were developed to better protect expensive racing engines. A
filter was needed that would handle a continuous high flow of oil
while filtering out small particles. The flow should not be
restrictive even when the filter is partially contaminated and all the
oil should be filtered all the time. The element should not be
affected by moisture which erodes paper elements, and it should
withstand pressure surges without collapsing or rupturing. The filter
element meets these requirements and overcome the shortcomings of
conventional filters. In the years since their development these
elements have proven themselves in NASCAR, SCCA, IMCA, IRL, and NHRA
racing and on countless street miles.
Conventional
spin on filters have an element made from porous material (usually
paper) which catches contaminant’s on its surface. The flow
limitations of this design require a compromise between large pores
for more flow, which also lets bigger particles through all the time
or a bypass which lets unfiltered oil during times of high flow. When
designing the filter this compromise was eliminated by going to depth
filtration, where oil flows through millions of intertwined passages
and contaminant’s are caught within the element. The flow
characteristics of this design allows for finer filtration with
greater flow without the need for a bypass. The synthetic fiber
element material which is moisture resistant is sandwiched between two
steel cages for surge protection.
These elements filter out particles down to 8
microns, half the size of what the average spin-on filter
does and has a flow rate even when contaminated, that is far greater
than that required by any automotive application. Depth filtration
extends filter element life because it can catch far more contaminates
without restricting flow. Because of it’s longevity these
filters are a natural match for use with the longer lasting synthetic
oils.
Lightweight aluminum remote canister housings
are available for both the 2 5/8" tall and the 4 5/8" tall
elements. While these styles have been most popular in racing, they
are a good option for applications where a conventional spin-on is in
a hard to access place. CM spin-on housings are offered for both the 2
5/8" tall and the 4 5/8" tall elements with thread and
o-ring combinations that fits most engines. These machined aluminum
housings will last the life of your car.
The technology in the automotive area has advanced greatly in
the past years. Today’s engines develop more horsepower from smaller
displacements, they rotate at higher R.P.M.s, with tighter tolerances,
and generally run hotter. To maintain longevity under these conditions
engines require a strong lubrication system. Today’s oils have also
improved to meet these demands, by lasting longer, and lubricating
better, but even the best oil can only provide protection if it is
kept clean.
In an automotive engine, oil collects
contaminates as it circulates through the engine, these particles
should then be removed by the oil filter. Contaminant’s are present
in all engines.They are a by-product of the combustion process which
leaks past the piston rings. They are small particles of materials
caused by the wearing of internal parts. Hot spots within an engine
can cause oil decay (sludge) that needs to be removed. To be truly
effective an oil filter needs to filter all the oil that goes through
the lubrication system and remove these particles.
Depth filtration removes more particles
without restricting flow, providing the absolute protection needed.

| Questions
Most Asked |
| Can
you clean Synthetic Filter Elements? |
| No.
Elements can not be cleaned because they work on depth
filtration design where particles are caught within
millions of tiny passages which run through out the
element. This design allows for a much greater flow
and the ability to hold far more particles than a
conventional surface filter. |
| When
should I change my filter element? |
| Under
normal operating conditions we recommend a
filter element should be changed every 10,000 street
miles. Many customers change the element every second
oil change. Under circumstances when large quantities
of particles are being caught, like in older engines,
engines which have not had regular oil changes, new
engines during break-in, or when some oil additives
are used, the element may need to be changed sooner.
When the normal operating oil pressure has decreased 4
lbs. to 5 lbs. the filter should be changed. |
| How
often do I change the O-ring seals? |
| Unless
they are damaged they can last at least 4 filter
changes. |
| Do
these Spin-on Filters have an anti-drain back valve? |
| Yes.
A flapper valve allows oil to easily enter the filter,
while preventing it from draining out once the engine
is shut off. |
| Do
the filters have a built-in bypass? |
| No.
The high flow of the element can handle more flow than
that required by any automotive application, so all
the oil can be filtered all the time. |
