My AFE Cold Air Intake is installed, and looks great, but I have not drove or tested it yet, but had a BMW Mechanic intall it for me for 75.00, and I will get my BMW back on this Monday when I had some more work completed. (ask me again on Wednesday)

I did it prior to having my Dinan work done. Noticeable power bump (not huge but pretty good BHP/$ ratio - infinite), and you'll also notice slightly more intake roar (which is a good thing... )

I saw about 15-25 miles more on a tank of fuel after I removed the Charcoal filter. I am basing this off 3 tanks prior and 3 tanks after. No difference in driving styles.... Cannot feel any power difference.

This is from my Petro 550. This was in the top filter housing and removed.
