Heh. No, I say that because I understand how increasing intercooler effiency (over stock) reduces charge temps on a forced induction vehicle, even if that air is sourced from under the hood, opposed to the anemic effect of adding additional piping (ie: length) to make an intake a true CAI. Sure you can maybe reduce intake air temps slightly, but any gain you might get will most likely be offset by box materials and the added length of piping. That's why no intake to date TESTED INDEPENDENTLY, has shown any real world gains but adding a more efficient intercooler can and does. I can see how the 2j intake could make a bit more power (because it is MUCH shorter, more of a RAI than a CAI, working on cowl induction principles). The biggest factor is that an engine is just an air pump and in the FiST's case, restricted by it's small-ish turbo. How to make more power = getting more air in (intake side), processed (combustion) and getting that spent air and gasses out (exhaust side). If the exhaust side is a restriction, little to no gains can or will be made on the intake side (and vise versa).
With that said, my intake charge temps are 3-5 degrees warmer than ambient on a 75 degree day. Air intake temp is 83-85 degrees moving. Even at full boost running through several gears, I never see more than 3-5 degree difference as long as I am moving. That ain't exactly "hot" LMAO.
Yes, there's a bit more heatsoak on hot days, but that lasts approximately 3-4 seconds after I start moving and temps come down VERY quickly (compared to the stock IC).
