just so that you are are not confusing yourself, the MAF is the MASS AIR FLOW sensor, it is a cylindrical black plastic piece that goes between the airfilter and the dryer duct type tube that goes to the intake of the turbo. the MAT, MASS AIR TEMPERATURE sensor is a small metal peice that used to insert into the old air box...it can be put anywhere, unless under hood temps go below -40 or above something like 250....(not sure of the actual values) the computer doesnt really care....correct me if i am wrong...
