Too funny. I've been this route several times. I had a Bama 91 Race tune and 3.31 gears and KandN drop in filter to start. I bought an Injen straight tube intake first. Got it used for $125 and it sounded great but I felt real sluggish under 3,500 rpm and hardly noticed the pick up in the higher rpm after about 15 mins of driving. Engine bay temp may have been a factor. So I sold the Injen intake. (Now I didn't change my tune from when I got the Injen intake. I sold the intake and reinstalled my factory intake with the Injen intake Bama tune.) Stock intake was so much more responsive and I really felt the pick up down low a lot more. After a couple months I missed the sound I had so I bought an Airraid plastic tube intake. Figured the plastic would shield the heat better. Felt better power up high for longer but again felt very boggy and throttle was not as responsive as my stock intake. (I had also installed a new tune for the Airraid just after installing.) After a couple months I just got tired of the feeling and went back to stock...again much better down low pick up and throttle response improved greatly.
After selling the Airraid some few months ago I'm missing that sound but just can't justify paying over $100 for metal tubes that retain heat and rob me of power. I will try one of these Ebay knock offs after I install my shorties. Maybe the shorties will help. Other than that I feel it's a waste to get an intake until after youve made some upgrades to exhaust. It's the only thing I haven't done ( 2012 GT H pipe are my only changes after selling the Airraid and returning to stock intake and KN drop in filter.) I do miss that burbble I'd get when I had an intake though.

Having said that, if you really think it was the heat, i have two ideas: a carbon fiber or fiberglass tube may help. The resins used in their construction generally have good heat resistance and insulating properties. An additional fix is to wrap gold tape around the intake tube. This is used by a lot of racing teams, as gold deflects heat well and the tape is relatively lightweight, but it's not the prettiest solution.

I have a feeling it wasn't engine temps if you felt that much of a difference. I think it's more likely that the tube diameter didn't match the stock diameter (if you didn't retune), that the tune assumed a different diameter than it had (if you did retune), or that the filter itself sucked (pun!).

Oh and to add to your idea. Wrap the intake but also wrap the headers. I know those cast iron manifolds can really radiate heat and after market headers are no better. Come to think of it I should wrap my BBKs before I have them installed.

I went through about 3 different tunes with each intake installed. Plus it's well known that the intakes available for our cars are not "true" CAI, they are short ram. The filter and air it is sucking in is distinctly hotter than the air outside ( unless it's summer then who's to truly know). Either way I feel the best way to go while your relatively stock is the stock air box with some kind of aftermarket drop in filter...just my opinion.

Yes, they are short rams. But, I think if temp is the cause, it's more likely because you're removing the stock box (which pulls air from outside the engine bay) and switching to an open element (which pulls hot air in the engine bay), not because the air is heating up in the tube. I think you'd be best served, if going the aftermarket short ram / cai route, getting one that doesn't pull from the engine bay, but retains the factory cold air port in the front.

I'm not sure if it's a good idea to wrap the headers. I have a feeling that the temp of the headers is going to exceed the working temps of whatever you're putting on it, and you run the risk of burning things. There's a reason that racing teams wrap the intake tube by not the headers.

I've seen and used header wrap before and it's worked just fine as far as not burning or catching fire. It's just a matter of if you feel it's worth it.

That is what I was trying to get across. By installing the Injen aluminum intake then the Airraid plastic tube intake and not seeing a whole lot of difference. The stock box a lows for you to get to the air directly from outside rather than the hot air inside the engine bay that all these other intakes pull in.

No. Very few I've seen actually reuse it. Even still they have heat shields rather than an incasing the air filter as they should. K&N does have a full box that surrounds the cone filter as well as reusing the stock cold air port. I've also seen an AEM, but I haven't seen it for less than $300. Too expensive IMO.

I did see a cool tut on youtube on making your own surround out of carbon fiber or glass fiber, but it is pretty freaking hard to get it to look good.
I really wish there was a WMS intake for the 11-14 v6.

Yea. SpeedyJoe tried out the k&n and I don't think he was very impressed with it. I want to say that i've seen a few that use the port, but are mostly open, so i dont know how much that changes the intake temps.

1. the housing is to small for the filter to get a real good flow.
2. the carbon cover is not made to perfectly fit and is rattling at WOT, so I had to change that. Added a layer of aluminum tape to the bottom for heat protection and strength. To close the gap between cover + housing I applied a thin layer of silicon which cured the rattling.
Performace wise I didn't recognize any increase in power and I changed my tune quite a few times with different values! The sound is o.k. after the mods.
Further more I even applied 2 layer of temp insulating color, I am not sure if it changed anything but the measured temps outside/intake matched!

What do you mean temp insulating color? I'd like to try that if I could. I'm thinking of modifying my stock air box to fit a cone filter using a generic ebay intake. See how that would work

I found it in a hardware shop, it is a color you can even spray on the exhaust manifold or headers and it won't burn off and at the same time has some insulating capabilities. Applied in multiple layers (I applied 2 thick layers) it should help keeping the intake temp near or equal the outside temp. In my case it did.
Sure, when standing still the temps will rise cause of the low airflow but as soon as you're moving it'll drop and stay low.
For modifying your airbox, I'd put some aluminum tape inside the box and some color on the outside. For the cone, you can buy any brand and use the available adapters. Just make sure the cone fits, there are tons of them out there. Airaid, K&N, ... are offering different sizes.

OK I looked on amazon and found Engine Enamel high temp paint by Duplicolor. Basicly paint that won't burn or fade under extreme heat. Didn't think to use it to reflect heat though.

Header wrap! I have some left over, I'll try that out and see. I managed to adjust and fix the fitment issues with this cheep off brand intake. Not bad...when I reported the fitment issue they sent me a new intake tube free of charge and since the metal is so soft a simple dremmel bit attached to a cordless drill allowed me to modify the faulty tube so now I have 2 intakes and all for under $100. I'll post pics once I can get a day shift off...hard to post pics at night.

I'm going to cut the second pipe to fit with the stock airbox and try that out too. Also I think making the breather valve that connects to the intake a little bigger might help out a bit. I did that with another car i had and it smoothed things out pretty good.

The install is extremely easy, you just replace the resonator tube. The MAF sensor remains at the stock location! The sound is a bit louder than stock but nothing compared to a CAI. Combined with a K&N filter you get a much better, unrestricted flow. The tube is shorter and much more direkt to the throttle than any CAI, therefor it won't absorb that much heat in the engine bay!
