The AEM intake has a 6" adaptor and supports a pretty big filter. My filter dwarfs all those in the test

I've seen those; the K&N FIPK/Typhoon also uses a 6" MAF adapter.

Kracka and MAPerformance, thank you very much for the test it was very informative.
I don't think nobody was complaining that the stock airbox wasn't tested. They were just asking why it wasn't. I know I wasn't complaining when I asked. I was just curious. A nice baseline would've been nice, but hey it really wasn't a big of a deal so I don't know why your making it one.

Thanks again for the test guys. I was dead set on ordering the Apexi intake, but I'm not so sure as of yet. Like I said in my previous post, I don't mind giving up some HP for some TRQ.

Well I guess many people want to know how much they gain if they put some tuning stuff into their engine. So the stock filter is the best reference.

Thanks for this test!

I KNEW my K&N that came with my ETS Intake was screwy. This just confirmed my suspicions.

no filter made less power, I find that impossible and therefore your test needs to be redone. At least you made an effort.

I have seen that in other tests as well but the simple addition of a Velocity Stack changed the way air entered the system and created more HP.

Granted, that was on V-8's but I would think the principle is the same. May act like a Venturi.

The proof is in the results; two filters beat out filterless, and filterless got 3 dyno pulls just like all the filters did. This goes to show a good air filter is very little restriction to the intake system and helps by smoothing out the airflow before it gets to the MAS.

I concur with the velocity stack concept. K&N does not incorporate this and this would also explain why the no filter test did worse than some of the filtered tests.

So...you're feelings invalidate our actual testing?

It's a dyno and not a lab. There are some variables out of our control and it's not a perfect representation of real world, on-road, conditions. However, everything we did was as closely controlled as possible and provides a pretty good unbiased power comparison amongst most of the popular filters for the Evo.

Very interesting results, thanks for posting. Looks like it is time for me to get a new filter.

BTW does the Perrin filter have a velocity stack incorporated into its mounting flange? I know that K&N filters do not.
