Intake Cleaner

[climb.on]

Either, I don't know how to use the search tool or it just doesn't work very well...in either case i can't find what I'm looking for...

Anyway, I remember coming across a post that talked about adding a cleaner of some kind to a vacuum hose that pulled the cleaner into the intake and cleaned in out. It had pictures of which hose to use and what the name of the cleaner was...any ideas?

I'm actually looking to do this with my '99, but I thought the post was in the 4th Gen Forum...
