Whats up i bought a K&N filter and i decided to take the cover of the MAF and i bought an apc universal tube but had to take about 8inches of of it so it would all fit but down to my question what exactly is the hose for coming from the oil fill spout to the inlet tube right before the TB? Also i want to take of my smog and a/c i have the deletes but what do i use to plug all the openings that are left and what can i do to make my engine bay look clean i will post pics of how it looks now if u need to see to give me some advice its nasty as h*ll
