Al does recommend intake, as well as BR, cool. But all i'm saying is why waste the money when it's been proven to provide little to no gains, and stock has no restrictions. Like i said, i'm not going to dig up the studies done, but i have seen plenty, search for yourself. Warr went 12.0 on stock intake, you think he would have ran 11's w/ a cone? DOUBTFUL. Looks like he saved himself $200, i would rather buy race gas.

Yeah, I read the thread and it backed what I was saying. If you would have done some more reading in Al's forum a gentleman lost 11whp and 4ftlbs by going back to the stock intake w/K&N filter from the HKS piece with moderate at best power levels...

Ill take 10whp any day of the week for $150. This argument is a mute point from here on out given this information. Next...

why would they recommend keeping the stock intake when they can make money off all the newbs

Yeah, Al doesn't sell these intakes - he just provides the info to us that he learns from tuning/dyno'ing so many Evos.
However, regardless of the gains you see on an intake ON A DYNO, that does not translate to road power with the hood down.

War, you should know that given the aerodynamics of the evo the hot air is relieved through the hood vent. The air under the hood is not stale like it would be sitting in a room on a dyno. If you leave the stock snorkel in place, cooler air is being directed towards where the cone filter sits.

WHOOPS...sorry... 
To some degree yes, but the air is still not sealed off from the engine heat like it is when using the stock airbox.
On a dyno, the stock airbox gets nothing more than the fan in front of it, which the open element intake benefits from just the same, if not more. It's not like that with the hood down on the road OR on the dyno.

I generally take Al's findings with a grain of salt. If you are going to mod based on one person's findings, why not take into consideration other tuners/vendors findings? Vishnu guys are running their stage 2 and 3 kits with stock boxes making over 400whp. I know a couple guys making over 400whp on a Mustang dyno running the stock airbox and a 20g-9 and race gas with a flash
The fact is, the stock airbox is perfectly fine for anyone running a stock turbo or equivalent. Most of the people in this thread are wanting an intake based solely on the sound anyways. Aftermarket intakes flow inconsistant air past the MAF...even with a tune, there is no way to regulate airflow through a cone filter. It may look pretty on the dyno with a fan blowing the same amounts of air constantly into the filter, but as soon as the hood is closed and irregular amounts of air are moved across the surface area of the round filter, you are going to see irregular MAF readings...the factory airbox regulates that airflow for the factory MAF sensor to read

Reggie, the JDM MR DV (stock IX BOV) makes almost no noise with the stock intake. It's purpose is not to make noise, but rather to release pressure when under boost and letting off the gas so that the compressor wheel is not damaged.

Ok, thanks for clarifying that
I didnt know
That's why I'm a noooooob Another noob question in regards to the JDM BOV, is it better then the USDM BOV?
I heard from someone that it increases the boost by a few, but I'm not sure how?

Reggie, please change your profile to show what Evo you have. If you truly have an Accord, then you're wasting our time a bit with these questions. If you have an Evo and need this info to make decisions, then we need to know if you have an VIII or a IX. The USDM VIIIs (03-05) all came with a plastic BOV that is crappy. However, the USDM IXs all came with an aluminum BOV that is identical to the JDM MR DV. It is an awesome unit that performs flawlessly up to 24-25psi. No, it does not raise boost - not sure where that came from. I recommend not listening to "someone."

LMAO!!!
You're kidding, right? That has to be the best response I have ever read on here. I dont think I can ever take another thing you say seriously after reading that.

Ah, sorry about that guys, I was reffering to the IX's.
Just wanted to clear up that question.
Thanks
