Superior Filtration:
This should be the last oil filter you will ever buy! Made from laser cut, medical grade, 304 stainless steel micronic filter cloth, this filter provides 200% more filter area in many cases. Most good paper filters will pass particles in the 90 to 95 micron range, and some tested, as much as 300 microns. Sand is about 125 microns and a white blood cell approximately 25 microns. Our stainless filter catches items down to 35 microns "absolute", which is about 3 times better than most good paper or brass filters. The pleat seam is welded, able to withstand up to 600 degrees in our filter, not glued, like paper filters.

Cleanable and reusable:
Simply remove the filter, rinse in clean solvent and replace it, you're done. The filter can be cleaned with solvent, kerosene, aerosol carburetor cleaner, or any other degreasing agent, even common dish soap. You can even blow air through the filter from the inside out to remove any small particles or cleaning agent from the screen if you so desire.

Consistent flow under all conditions:
Stainless steel will stand up to the stress of heat, high pressure and physical handling much better than paper or brass. This filter maintains consistent flow under all conditions including cold start ups and or under extreme heat. A one inch square of this micron filter material will flow 1.9 gallons of 90 weight oil per minute at only 1 psi pump pressure (70 degrees F). Our typical filter size is 30 sq. in. which equals the flow of 57 gallons per minute. Standard paper filters do not flow well when the oil is cold, often causing the bypass valve to open allowing unfiltered oil to enter your engine, uhg!

Unaffected by Water, Heat and Pressure:
This filter is capable of withstanding extremely high pressure and flow rates. It is also unaffected by Water, Heat and Pressure, unlike standard paper filter material which swells in the presence of water, closing off filter pores and reducing flow.

Early Detection:
By allowing you to inspect the debris that is in the filter you can monitor your engines condition, avoiding minor and or catastrophic failures.

What is a Micron?
A micron is one thousandth of a millimeter. That's about .00003937 inches. Fine sand can be as small as 62 microns thick. Our filter will not allow any particle over 35 microns to pass through this filter, that's some pretty small stuff that's being caught.

So who uses this type of filtration?
This high tech filter technology is widely used in all types of auto racing including NASCAR, Indy type cars, Formula 1 and in the Aerospace industry where filtration is of the utmost importance.

Things to think about:
Next time you are fanning your clutch think about all that tiny debris that is created from the clutch and gears meshing together, spinning around in your motor's vital parts. If you really care about the life of your motor and consider the cost of loss of time associated with a current day 4-stroke motor, then you need one of these filters. It's even transferrable in some cases to your next bike. I used the same filter in my last three bikes, and it's still like brand new, there's simply nothing to wear out.

Environmental benefits
In addition to all the other benefits, our filter helps keep the land fills free of old used filters.

This filter is proudly made in the USA.
