yeah the TB is cocked a tad, i think 45 should work fine though....BUT!.....the 3 inch pipe WILL NOT work if your like me and just going for the "stick pipe in accordian tube" method......sooooo im not sure what im gonna do...i dont really wanna mess with the IAT...id like to leave it where it is cause im not sure how to move it really....im going to ask around on some truck forums(they have big exhaust and see what i can find.

drill a hole in the metal pipe for the sensor.

Get a filter that has a hole for the IAT sensor.

Don't stick the pipe in the accordian, you'll make it VERY turbulent like that. A 3" rubber coupler is $3 at any home improvement store for pipes. It'* not as giving as silicone, but it'* not as expensive either.

If its very turbulent, will it idle bad? Or is there any notice?

allright whats an example of a filter with a ready made hole? part # maybe? ill probly just end up getting a K&N. i take it none of their universal filters have such a hole? and what size reducer do i need? 4 inch to 3 inch right?....and does the IAT come out as one piece or what? i havent really looked at it that much....thanks again for being so helpful. but in case you havent noticed im kinda ignorant so i need ppl to hold my hand and say "buy this"

Just what I was going to say. 3" pipe coupler, bud. That make the outside dimension 3 1/2". Here'* a pic of mine. I used all PVC. Notice the pipe coupler that the filter clamps to:




The one you want will be rubber fot the metal tube.

k&n rx-4750 has a IAT hole.

Actually, if you look at my pic above, the piece the connects the PVC elbow to the TB is a 3" rubber coupler. It will be black like that. Now that I think about it, the one you will want is a 3" to 3 1/2" coupler with a 3"-4" long piece of tube to attach the filter to. The rubber coupler will not be stiff enough to clamp to.

In any case, do whatever you can to stick with a 3" pipe, or you'll defeat the whole purpose and won't gain anything.

Dude...enginebrite baby

Go to truevalue, ace.etc... and get a 3.5 to 3 inch rubber connector. called something like a elbow to pipe connector. i have one and has been working for the last 5 months, and very flexible unlike the other pieces you will see at the store, so make sure you dont get a stiff one.
