Default How to cool my intake air temp

What can i do to cool my intake air temp?? generally on a 60-70 degree weather day my intake temps are around 110-120. i looked at my buddys and his is consistently 91-92 degrees. Could my ewg be one of the causes?

Heat wrap/ shield everything possible. I have My TMIC wrapped in gold reflective tape, as well as shielded my firewall by the downpipe. Working on wrapping my twin scroll manifold and putting the factory heat shields back on. From what I've seen/ read, the manifolds are the biggest issue since heat rises. My friend also told me his EWG raised his IAT. Subarus do generate a lot of under hood heat. If it's that bad, look up JDWhite from Australia, He added louvers to evacuate heat and has some testing to prove it, although he seriously tracks his car.

EWG should lower temps since it's dispelling the heat preturbo (assuming you just went WOT)

Unless you're using an aftermarket IAT sensor, I wouldn't trust the readings from the maf.

You can do water injection to lower the temps. Not tuning for power, instead to lower temps and it's great for pre detonation

why not? Assuming the OP is using the stock maf ..any readings from the iat in the maf is what the ecu is using and trusts for fuel/boost/wg compensation.

because stock IAT is pre-turbo, pre-IC and the only thing it can give is temperature tendency depending on x factors
