Best Cold Air Intake for HP Gain

Anybody who "feels" a power difference, either way, from an intake on a 2IS is imagining things. (or confusing louder with faster)... You're talking a swing of 0-5 hp tops.
Best bang for the buck remains the Joe Z pipe at 5 for $125.
In fact that's the best bang for the buck hp mod for the 2IS period at $25 per hp.
Compare that to folks dropping $600-1200 on a +7 hp axle-back exhaust, they're paying $85-170 per hp. Which is kinda nuts.

AEM claims 11hp with their ETI intake system. They even provide a dyno chart to back their claims. The intake comes with a module to plug into the MAF.
I have it on my car and it does feel like it pulls a bit harder past 3k rpm.
This article confirms it added 6hp and 8lbs of torque on their tests.

That's why independent dynos are important.

yes, but they are lying. So is K&N with their hp claims, and most other intake makers (Joe Z being one obvious exception)

You are confusing "louder" with "pulls harder", which happens a lot with intakes.
So about half what the maker claimed.... and nearly identical to what the much cheaper, doesn't-screw-with-your-sensors, Joe Z intake produces.

I just found your comment very, very funny...
And I do agree that everyone has the right to personal preference..
Keep in mind guys, the design I make is because it works.. Since 2006...

I installed an AEM and noticed a small difference. Mostly in second gear. I have an 08 is250 6mt. It's for sale of anyone wants it. I'll sell the intake for 220 Shipped in USA. It has about 300 miles usage on it.

I can't see the intake adding anything more than 5hp. The 2IS already takes in more air than it can possibly use. With that being said, the 2IS stock intake tube is ridged which can cause turblulence which I believe the intakes we purchase aren't really "adding" hp but rather "restoring" the hp that should have been there through a smoother tube by corrective means.
Now if we look at the axle backs we purchase, I've noticed the stock exhaust has a poorly designed Y-pipe which is why we "potentially" get more power but it's still after all the cats and resonator of our car which again leads me to believe the axle back gains you no power. Rather any power gain on a dyno is simply within a margin of error.
