Why Choose A CM Filter?
CM 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 CM filter element meets these requirements and overcomes 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.

How Much Do CM Filter Elements Filter Down To?
CM elements filter out particles down to 8 microns, half the size of what the average spin-on filter can do, and have a flow rate that is far greater than that required by any automotive application even when contaminated. Depth filtration extends filter element life because it can catch more contaminates without restricting flow. CM filters' longevity make them a natural match for use with longer lasting synthetic oils.

Can You Clean CM Synthetic Filter Elements?
No. CM 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 CM Filter 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 My O-ring Seals?
Unless they are damaged they can last 4 filter changes.

Do CM 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 CM Filters Have A Built-in Bypass?
No. The high flow of the CM element can handle more flow than that required by any automotive application, so all oil can be filtered all the time.
