I removed my CAI a week or so back to clean it and after I pulled it off, I noticed a bunch of oil on the bottom of the plumbing. I have read the threads here about the catch cans but never thought it would really be required. With the amount of oil I saw; it's definitely needed. Because I left the factory fresh air intake plumbing intact after installing the CAI; I was not able to use the two BSH suggested installation locations for the Catch Can. The rear most point did not have enough vertical clearance even after I tried moving the bracket and or making a custom bracket. The bottom of the can kept hitting the fresh air plumbing. So I found another option. It only required the purchase of 3' of 5/8 hose. And it's still completely reversible.

 

Nice install; Good job as well as finding a solution to mounting the catch can. If you have run into this problem, we also supply an extra bracket to mount the catch can along the firewall next to where you have done so on your strut tower brace. Thanks again for the purchase, and keep us updated as to your findings of whats inside!
