I bought a used Blackwing from a member on the forum. It probably is simple, but are there instructions out there? I want to be sure I'm doing it right. There's a hole next to the 'sensor' on the blackwing. What do I do with that hole?
That's for the PCV valve. You pull the original valve out of the old air box and plug it into the Blackwing. I had to trim several inches off the PCV hose to make it sit right with the Blackwing. You don't have to do that though. Hope this helps :)
