It's part of the MAF.

 

the iat is pretty much the same as a maf u might also be able to get away with a reflash but try to calibrate first.

 

THank you s much guys. i changed back to my stock maf and the car runs awesome now. only thing that i got to try and figure out is how cold the car is running all the time...might be because of the lack of a winter front. but it runs great now. i made a trip to the city doing between 120 to 130 (i was running late) and i got 400km to 43 litres. i shouldnt expect any better out of these v8"s right?

 

Glad to see it's a lot better.
