This is a very interesting! Sounds like a choice of how much air or how much dirt do you want getting into your engine. http://www.bobistheoilguy.com/airfilter/airtest1.htm click on the links at the bottom of the page. | ||

The sentence 'For the record, the K&N was the best flowing filter' says all I want to hear. Mind you, another sentence, 'Again, this is a very low budget test, ' says I didn't want to read it anyway  | ||

I currently have the F.A.S.T. Kit w/ the k&N filter and no airbox cover and wouldn't change a thing. No problems to speak of. Revs right up.  | ||

(scratching head) I believe he's talking about the K&N OIL filter, not the air intake filter. I use K&N oil filters on everything in my garage. | ||

I would like to see a pic of his "air flow" testing jig. First off its not a "Air flow test" Its a air press test that he is doing. Here is something to think about, flow(amout) and pressure(force) are to different things especially when hooked up to an intake. As pressure goes up the intake would intake it. Leveling it out to some degree. Thats the whole purpose to get more air in through the intake. The way to do this test is to use an actual air flow meter. Never the less his pressure test is kind of entertaining. "I also put a test port on the airbox housing after the air filter." I am pretty sure if you wanted to measure this press test accurately he should of used a different manometer. One that allows for a more expanded scale. Like mm not inches! -Manometers measure a pressure difference by balancing the weight of a fluid column between the two pressures of interest. - What he did next is pretty funny is. "All of the measurements in inches of water were taken at 6500 rpm at WOT in 2nd gear while climbing hills locally in western WA." While he was driving? WTF. LOL I could just picture this car ride. A U type mano meter must be placed stable,level and have a regulated temp to conduct a test that will have any validity. Othe factors are the SCALE, type of fluid, cross section sizes of the manometer. I truly would like to see this test done proprerly to really see how much air "flow" there was between them. I definetly wouldnt go by this test for any decision making. Its a shame I know they went through a bunch of work to try to do it. |
