<font face="Verdana, Arial" size="2">The K&N Performance Gold® Oil Filter has been constructed from the ground up to satisfy the high performance needs of race car owners and drivers, as well as the average vehicle owner who wants the very best oil filter available. Our oil filter's efficiency rating meets or exceeds the requirements of high performance automotive engine builders. The heavy duty construction provides over 550 PSI hydrostatic burst*, and helps reduce the risk of rock and stone damage.

The real quality isn't just on the outside... the inner filter element traps contaminant as small as 10 to 20 microns in size. We use metal top end caps instead of paper to ensure that no unfiltered oil can get back into the system. The solid construction allows for oil flow rates between 12-16 gpm (depending on filter size), and is unaffected by racing fuels. All K&N Performance Gold® Oil Filters are manufactured to exacting engineering standards. They are covered by a limited warranty to be free from defects in materials and workmanship when installed and replaced using engine and equipment manufacturers recommended service interval.

I recently interviewed at FRAM in perrysburg, OH. That is the filter division. They told me that one of their warranty claims deals with the fact that the oil filters they produce have different burst pressures. If you ever look at an oil filter, and it has a crown on it, like little dimples around the circumference, those little dimples act as stress risers. Oil filters are the weakest along these lines. (When metal bends, it gets weak). You may notice that their 'racing' filter eliminates this crown for just that reason. Another significant warranty claim is the lack of filter media in the filter, but you gotta love the sure-grip.
