Apexi vs K&N filters

optus3
Can anyone see any advantage of H&N air filters over the Apexi Power intake. There's not much price difference if you shop around. I know the H&N is reliable but looks old school.

You mean K&N, right? If you really want flow in a cone filter, I'd recommend the K&N X-Stream with the filter on the top as well as the sides.
There's probably nothing wrong with the Apexi- I like the fact that it's a dry filter, but for filtering properties or a dry filter with good flow, I'd recommend the AEM Dryflow filter.

but has the K&N X-Stream been shown to be any better than the APexi? Because that's why the Apexi is good, because it sucks air from all around.

The apexi still sucks from the sides, but that cone design on the top is supposed to divert the sucked air towards the opening, whereas the x-stream has the filter top, which I think should flow more.
K&N's wet filter tech (with very porous media) allows for a lot of flow, but only "adequate" filtration. I'll try to find the filter media study, but IIRC the K&N was found to flow the best, but for best combination of flow and filtration, the AEM dryflow was the best.
Regardless, any cone filter will allow for more than enough air for our engines.

thanks for your reply mtlswift,
I found this article on the net. Its intresting

Good find! Well, if it's true, go for the apexi. The difference in gains are moot. 1 hp variation can come from sneezing too hard.
Don't forget that the translators won't vouch for the authenticity of the test. But definitely don't get the sintered metal filters. They definitely don't clean very well, plus retain heat.

i just go with k&n cause i know the quality is good, they have been proven time and again. btw, this is the wrong forum for this question, just a heads up
