Anyone seen something like this before? I removed the air box and filter to install the Dali FRP scoop and a Uni filter. In the flexible, accordion tube between the air box and throttle body, was a white, chalky film on the inside walls of the tube. It wasn't on the throttle body or butterfly plate though, and the air box itself was clean too.

I sprayed it clean with throttle body cleaner and reinstalled it.

Haha. Some of those guesses are classic.

My bad for not searching... I started the thread while on my phone.

Thanks for the replies.
