You will need a 4" od 45degree ell and 1 4"clamp. I used a 3" id pvc ell which is 4" od on my truck works lake a charm though not a pretty as a mandrel bent 4" od steel one but it gets the job done.

Sometimes you can get a piece of 4" bent at 45° at Pep Boys or similiar store. My brother got his there and polished stainless.

If it is shorter than that it will be fine. Just as long as you can get a clamp and hose/filter on each end and clamp it.

Get a 3" PVC 45° elbow from Lowes or Home Depot. That will get you there and if you want to clean it up later you can get a steel one.

The PVC from lowes is what I used. If you paint the elbow black it will look a lot better than white PVC stickin out of the black tube.

And reading your first post I wasnt sure if you knew but I am stating the obvious. The entire stock filter housing gets removed. Tuck the air temp sensor that comes off the housing into your fender well.
