We've proven out that our intake systems dramatically reduce restriction and maintain radically high efficiency levels. We've also posted all of the results of our filters tested against the competitions at the following website.
The Truth About Filters
The testing that Tri-Valley did was not ordered by our company; this was independant dyno testing of an S&B intake. This test was something Erik did to see if our product performed as we claimed. At the time of the test, Erik wasn't selling our product. In fact, he was quite skeptical and decided to test it out before getting behind our brand. I respect that about him and it says a lot about the company.
We here at S&B have never claimed to make the most power, as that isn't our main goal, but Tri-Valley's test shows that our kits produce some pretty great results on the dyno too.
Our goal at S&B is to give you the largest reduction in restriction possible while still protecting your engine with a highly efficient air filter. We never compromise on the filtering ability of our products, so you'll never see one of our filters hit below 99% efficiency. I can't say the same for our competition!
