Dunno where you came from lol...but welcome.

I too was adamant about not changing the stock IC...citing that it doesn't really get heatsoaked, and if IAT's climb, they recover almost instantly. I quickly found out that is not really the case.

Not sure where you live, but here in AZ I saw 150F+ IAT's with the stock IC. On that occasion it was about 40F+ above ambient. Not acceptable for me, and bordering on dangerous. The amount of timing being pulled was incredible. And trust me, once the temps get up there...they really don't recover. At best, I would never see below 10 above ambient, and they would just climb up from there, amazingly quickly.

Fast forward, put the Helix IC on. WORLD WORLDS WORLDS of difference. You have to really beat this crap out of the car to get them to go more than 15 above ambient. Most of the time they hover 5-10 above ambient during hard driving. Whereas the second your on it with the stock IC, temps skyrocket.

I honestly was expecting to not feel a difference after installing it, and I went into it with low expectations. Boy was I wrong. The difference really is astonishing and I suggest you take another look at how grossly ineffective the stock IC is. I have been told that MINI is even doing a re-design of the stock IC because they were not satisfied with it. Aside from maybe a turboback, going with an aftermarket IC on this car provides the single biggest gain out of any bolt on part currently available.

I will agree with you though that with water/meth, the IC becomes pretty irrelevant. However, not many of us have them, and I am not satisfied with the ones available currently. So for now, the IC is the best way to go.
