It's a pain to put in and IIRC, even though I bought SU's, it doesn't fit perfectly, but it was close. What worked for me was to put it in the mounting bracket on the engine, loosely attach it to the IM, before I had the IM bolted down, then loosely attach it to the EM, by maybe three or four threads on each side. Then I tightened the IM to the engine, tightened the IM side of the EGR tube, the EM exhuast side and lastly the bracket. Now it fits fine. Initially, it was a pain to get it on the EM, because I seemed about 1/4 in too long.
