That's exactly what I was going to say.... Ha.

Doing the same thing myself. Can't use all that power in the winter with snow tires anyway. No rush.

Exactly, just need to find a Cobb dealer/installer.

While it won't necessarily get lower, it will stay low longer/more consistently and will help the IC disperse heat faster/more easily by pulling in cooler and denser air from the start.

Big question is it worth the $325 for what seems like a marginal performance gain if any? I'd like to see datalogs.

You people and your datalogs. "I wanna see datalogs, wah wah waah..." Damnit just buy what you think works, ignore what you don't... Modding cars is "pay to play." Would it be nice to see data, sure. But data shouldn't be the end all, be all of the matter. This is my opinion and it may stink, but I don't think you can have fun and really call yourself an enthusiast if you're always looking for the data points. Just have fun with it, do what your wallet can handle.

While I understand your point and will let it stand here. Please keep on topic and not tear down others that may not have the means to afford every upgrade and want the most bang for the buck .. We all have different ideas of what we want. Thank you

the design and price point of the Cobb intake is really attractive. I wonder how heat resistant the plastic is versus aluminum or rubber or silicone. I am not worried about the plastic deforming under heat, but rather the ability of plastic to insulate the intake air from engine compartment radiant heat. Chances are good that if I go with this intake, I would wrap the entire thing in gold foil. Hopefully there will be some good videos with the intake sound under load, along with any data regarding performance increases. Right now, I am happy with the drop-in filter, modified lower air box (which would work with the Cobb intake), and gold foil wrapped tubing. At some point, I might want to go for something different and the Cobb or Mountune are on the top of the list.

Aluminum is a far more thermally conductive material which has the ability to conduct and transfer heat much more rapidly than a thermo-"filled" plastic material which Cobb's uses to form their Intake tubes...And this thermo-filled plastic used to create the tubing is also similar to the material used to create much of the stock piping found in most vehicles today and for very good reason as its highly durable to both mechanical stress and high heat conditions and is far less thermally conductive (or far more insulating) than using aluminum...It may help to understand that this is not a simple plastic used and is a composite thermoplastic material created by infusing either fine silica or ceramic material within the plastic to improve both durability and also acts as a fairly good insulating material....

Same reasoning applies to why you'd want to either keep the stock airbox or redesign a new one using a similar thermo-filled plastic material as opposed to using an aluminum box particularly when its located within close proximity to the engine which can create quite an oven effect...

Some people in life like making educated decisions when they "pay to play". I know, it sounds crazy, right?

My opinion is your opinion stinks. You can't be an enthusiast if you care about the data behind all of it? Isn't that a version of being really really into something, aka, an enthusiast? I think that makes you even more of an enthusiast.

You think I do all my data logging and tuning because I don't give a crap about this stuff? I'm not selling anything but I am sharing data and tuning with the community because I'm not an enthusiast?

I agree 100% with your comments. Aluminum is the worst for thermal conductivity, or best actually which is the worst for trying to insulate the air from heat. I would guess the silicone is the best due to the thickness and silicone heat absorbtion rate compared to rubber, next is the Cobb intake, and then the OE rubber. All the materials would benefit from heat reflecting foil as it reduces the heat on the surface of the tube which can be transfered thru the material to the air stream.

Since I was admonished once already and we were asked not to stray too far off-topic, the intent of my post was to denote that sometimes you have to just go for it; there are several manufacturers with different price points. There are key words in my statement strategically placed to dissuade arguments that would arise from the statement itself. If those key words are glanced over, the meaning of what I've said will be lost and misconstrued in an attack on me. There's a difference between those trail-blazers doing the legwork and the followers who loll in the cleared paths. If you want me to clear up my post further feel free to PM me; otherwise, I wish to respect Rod's wishes.

It would interesting to test this to see how effective wrapping the intake system would be by monitoring "before and after" intake temps during idle over a predetermined period of time to determine how much a benefit would be gained by foil wrapping the pipes and box...

Evo guys have that data. The Evo 10 guys go crazy with that foil. Some of their engine bays look like the cargo hold of the Space Shuttle.

I have been watching the intake air charge temps with the foil, and saw a few degree drop in temps from letting the car idle stationary. I also don't have all the items wrapped that I want to wrap, nor have been able to get really good before and after numbers. I had started with the foil before my AP was installed, and finished most of the gold foil after the AP, so I don't have anything for stock. I wrapped the induction tube in silver and then with gold foil. The sides of the airbox near the engine and radiator have been wrapped in foil along with the tube going to the airbox from the bumper where it is near the radiator. I also have a small section of the cold side plastic tube near the block and throttle body. I condsider a few degree drop worth the time, effort, and cost of the foil. It surely won't hurt nor will it be the best thing you can do for intake temps. You surely won't get away from buying an intercooler because you wrapped tubes with gold tape.

For anyone looking at installing the Cobb intake, I would wrap the entire thing in the gold foil prior to installing it. Trying to get around everything with it installed isn't fun.

Lol, aftermarket parts venders must love you!
