i got a 2013 r6. broke a valve and ****ed up the original engine after 40k miles so i bought a used engine. the new engine has graves smog block off plates. my question is, what do i do with the plug that plugged into the thing the smog plates replaces. do i just leave it there not plugged into anything? and also that thing with the hoses turns to one hose which i think plugs into the air box. what do i do with that hole in the airbox? just leave it open?
