Retune with Takedas

^ I have yet to see proof that a CAI produces lower IAT than our stock intakes...

Seriously though, I would like to see proof if they do. Smoother air I can buy into more easily but that doesn't make a lot of difference until very high rpms. Sound and looks should be the dominating factors when going with a CAI.

If you guys need proof like that to justify CAI I suggest a easier game like checkers maybe.

I never said some gains weren't possible, but it is not because the air is significantly COLDER versus stock as you claim...

Show me all the high performace cars that come with an aftermarket style CAI from the factory...the automotive engineers all around the world didn't screw the pooch that bad.

I'm not hatin' on CAI either. I have had them on my previous vehicles.

I take it you aren't an engineer? And for the record I whoop a$$ at checkers btw

Back on topic now...still looking forward to results OP.

The problem is you guys need so much reassurance about products and what they do I'm surprised anything get sold,And I'm not a engineer but have been working on cars for a living for 28 years and don't need to be told what is what or any reassurance on what works and what doesn't my Rep and opinion in this community speak for them selves.

There's nothing wrong with a little reassurance before you spend a good chunk of cash. If no one needed reassurance then there's no point in ever dynoing a car...just data log your A/F ratio's while you drive around town and adjust the maps accordingly. No need to prove your HP gains to anyone and say "just trust me".

I'm not doubting your rep, automotive experience, or ability to work on cars but the physics has to make sense for a claim to hold water (or in this case air).

HP gains are possible with a CAI but NOT because the air coming in is any COLDER. That's a marketing ploy that just appears logical.

I'm gonna stop repeating myself now. My apologies to the OP for derailing further, happy Sunday!

The G3 and Takeda HP increase are probably result of the ram air effect more than "cold air" (especially on g35/37).

That being said cold air does have an effect. In this case cold air being ambient temperature vs engine bay temperature. Cold air is dense due to the molecules low energy level vs warm air whose molecules are more active. The higher volume of air entering your throttle bodies is sensed by your MAF which tells your ECU to increase the amount of fuel thus more HP. In an essence same thing forced induction does forcing MORE air molecules into the system only to a much larger scale.

And before you start trying to poke your chest out being you are an "engineer" I have a degree in aeronautical engineering...

...I think we're done discussing this, you guys are missing the entire point I was trying to make. Please PM me if you'd like to side bar.

I hope the OP comes back with dyno charts soon so we can bring this thread back on topic.

it doesn't! What it DOES do is it limits the restriction and turbulence of air flow. Stock intake tubes have ribbing type plastic therefore creates air turbulence, also it doesn't have smooth air flow into the upper intake manifold. Most of the cold air intakes are promoting cold air intake, but what it is really accomplishing is smooth air transition from filter to manifold. No ribbed edges and no turbulence creates even air flow.
