Interesting test. I have seen other tests performed the same way but with different results, ie the paper filtering the best, cotton middle and foam the worst. I have only used paper filters on my cars/trucks and have never had dirt go through it like they showed.
I find it interesting that they pretty much use a stock intake lay out, smooth it out with better parts and it qualifies as their true cold air kit. I kind of confirms to me that stock intakes have the right idea in getting the cold air to the filter/ throttle body, but they just have a rougher air pathway with all the resonators etc. If you have the resonators before the filter, it should be not an issue and some stock intakes can be pretty good.
I also like that they talked about how all filters flow way more air than the engine uses, as I have read this to be true also.
I am thinking that they don't really have a working website to do further looking....I am not sure how to even get a hold of the company either.
