Some of us have converted over to the 90mm LMAF and have been building our own Cold Air kits. I tried a 45* elbow on my setup with the C&L pipe but it wouldn't work without cutting the fender.
I think I may have found a fairly cheap 4" elbow in a very unlikely source.

It doesn't seem to have the big flange a lot of plumbing type elbows have. Plus it appears pretty durable. I ordered one today. I'll let you know how it works out when I get it. I'm curious about how thick the plastic is. It's made for airflow movement (with sawdust), so it should work.
