I have an 03 cobra and really want to know how hot the air that is actually getting to my heads is. Does anyone know where i can tap into after the blower to put a sensor for an intake air temp gauge. Also i wanted to hook up my a/f ratio gauge, does anyone know what wire off the o2 sensor is the signal wire? Thanks

Not sure about your first question , but as far as the a/f gauge, I heard that basically you are paying for a light show, not very accurate.

For the first one, the easiest thing to do is get an XCal2 for your car...it'll tune it and it can also datalog and it'll tell you your IAT temps...and Dr Wu is right, a narrow band A/F gauge is just a light show...All it tells you is if you are lean or rich, and there's a big margin of error there with the stock O2 sensors...and a couple points of A/F can mean blowing your engine which that gauge can't show accurately...

Hey thanks, im not to fond of seeing flashing lights while im driving. Do you know if the IAT sensor is located after the blower and if so where at? Thanks for the advice.

The IAT sensor is in the MAF on the 02+ cars I believe...
