summitracing sells vortec and trickflow elbows, if you look up your car they even have a "air intake elbow" section...they also sell them on ebay. This is a very common problem. A stock replacement one is 80-90 bucks, but a nice polished one from vortech or trickflow run around 75-110 dollars depending on the finish. I went with a satin finish trickflow one, ran me $82 with shipping I think and it looks like it's supposed to be there, looks very good.

I gotta post up pics soon. Really cleans up the engine bay.
