Race and performance parts in general have a much shorter service interval and life than the OEM, stock parts.
I suggest you inspect this filter, in the beginning, every 1,000 miles of regular driving to see how it stands up to the conditions you drive under and service it accordingly. If you are like many people who change their oil every 3,000 or so it puts you at 6-8000 miles but, that is just a number. Check it and service according to your conditions.
On the many cars and trucks I have seen in my shop every filter of this type, IMO, has been past the point where it needed service and that includes the NSX's. They were dark, heavy, and on the NSX's, with flat filters, had a dark clog slightly off center toward the intake. Not deep breathing, but smothered.
My opinion is that unlike a OEM paper filter, when the dirt hits the element, it absorbs oil and swells just like speedy dry or dirt does when it absorbs oil on your garage floor.
Up front this filter can offer better and deeper breathing/performance but, it can clog sooner with less dirt than a paper filter under the same conditions.
When the oiled filter gets clogged, the engine still searches for and pulls the same amount of air and could pull more air/oil from the oil breather line and foul your intake. IMO, cars with oil fouled intakes that use this type of filter are not getting residual oil from filter/box but from the breather line.
You need to clean the filter before it gets restricted enough to have this happen.
Teams who race, maintain and service filters like this after every event.
If Comptech had wanted you to clean the filter every 15,000 miles they would have said, 15,000 miles which BTW, if you notice is half of the service interval of the paper OEM filter of 30,000 miles. It will need more attention. Inspect regularly and clean accordingly.
Again, it will give you more air, sound and possibly a few HP over the paper OEM filter but, it is a much shorter service window.
