Anyone know where it is located and can tell me in laymens terms how to find it? I am a noob when it comes to finding stuff on the engine

 

The IAT sensor =Intake air temp is an integral part of your MAF sensor or the sensor that is on your intake it calculates timing corrections depending on the incming air temp be careful with ebay chips dealing with this as they will overadvance timing telling the air is coming @-50 degrees when its not

 

yo ever got that chip installed, i want to know if u can feel that differance
