I'm just as concerned about filtration as the next guy on BITOG, and S&B's website is the only place w/ most of the newer air filters tested against each other. I've looked through the results and in at least one case they chose the worst filter from the competition (True flow) to test against their own, but the tests results seem legitimate w/ PDF's that have all the info on the ISO 5011 tests.
For the Ford 7.3 L powerstroke in the course dust test their tests results show OEM at 99.76%, S&B at 99.69%, AEM dryflow 95.29%, and AFE dry at 93.44%.
Their tests for the 6.6 chevy duramax application show efficiency numbers of 97.46 for K&N, 97.99 for amsoil nanofiber, 98.26 for AC delco, 99.39 for S&B, 99.61 for Airaid, 99.77 for AFE pro guard 7, and 99.82 for Wix.
The aftermarket performance filters that do the best in the tests are Airaid, S&B, and AFE pro guard 7 all w/ efficiencies higher than 99%. All the info and PDF's can be found here air filter tests just click "skip" at the bottom right then "view test results". I know a lot of people are gonna say what about fine dust tests, but if a filter can filter out smaller particles better then it should do the same for larger particles, right? I'm just looking for some input from fellow members to make the best choice on which air filter to use w/ intake.
