I know we've beat this to death, but here's a couple more facts for you doubters of the efficiency of a K&N filter. Either the doubters forgot to oil their filters or didn't seal them properly.

"K&N air filter designs are tested both in house and by independent testing laboratories for air flow, filtering efficiency and dust retention. The Society of Automotive Engineers (SAE) establishes testing standards for automotive air filters. Independent testing of panel and round K&N air filters has confirmed an overall efficiency rating of over 99% when tested using the SAE J726 air filter test code. The test results provide scientific details including particle size, size distribution, testing methodology and results. The overall results establish the superiority of our filters against the "competition". The OEM minimum specification is 96% with ISO (International Organization for Standardization) test dust which consists of a majority of 0 to 5 micron particles but some up to 20 microns in size. Test results showed that a paper filter has a 99.29% cumulative efficiency and a 96.47% initial pass. A K&N filter, with far less restriction than paper, has a 99.05% cumulative efficiency and a 97.11% initial pass."

Re: More K&N crap...for those who care!

I'm not a doubter, I'll try anything once, anyone can fudge paperwork, I ran one for a year, oiled it with the kit by the directions, (cleaner and spray on oil) had the dirtiest throttle body I'd ever seen, threw it all in the trash, nuff said, all crap, never use another one will walk first.

Re: More K&N crap...for those who care!

I've seen those 'Independent Laboratories' testing procedures...
Who ever is paying the bills gets the nod..

Until SAE does the test, it's not done correctly...
I don't care for K&N, and too many failures with them in my dirt track days, and I really don't think anyone here is going to question if I know how to oil or seal an air cleaner are they?

I know guys that swear by them, but I don't know one major manufacturer that uses them in any of there kits... And these are the guys that have the ability to do unbiased testing...

Just my opinion from experience...
I'm not going to build a $250,000 flow bench to introduce solid particles into for filter testing, and invest another $100,000 for particle counters, so it will just have to stay my opinion.

So many cats, so few recipes...
