Man its Heavy! would take a lot of energy to heat up that thing. And assuming you are moving, it should stay at ambient temps pretty solidly. Sitting stopped in traffic, its gonna get hot and stay that way until rolling for a bit again I think. lucky I dont have any traffic near me!
Mine arrived today! 8) Packaging is fantastic. It's a real lump! Beautifully made. Makes the stocky look pretty poor. Complete with pictorial instructions. Love to fit it myself but not sure how risky it is to run the beast prior to a new tune and I have a 200k trip to the tuner. Anybody know what the risks are?
Spoke to a protuner who said it wont matter as my tune wasnt bleeding edge enough to let the cooler intake air affect AFR's much at all. Really all we are doing is reducing the chance of detonation by letting less unwanted hot air in. it doesent affect the tune too much, and if anything the car learns the reduced knock incidence with this TMIC and winds timing advance correction back up in your favour. Subarus are clever like that ;-)
Heres a crappy analogy.
Imagine Running on a gravel road in bare feet. if you hit a sharp rock, you slow down and become more cautious, The more shark rocks you step on, the slower you go until eventually, you are walking looking carefully each step, if you feel its smooth consistent underfoot and havent hit anything sharp, you can run fast, and really stride it out and not worry about the rocks underfoot. Thats what the learning around knock correction and timing advance does in our ECU's. so the TMIC upgrade is just one more thing to help give us a smooth surface to run on.
