Another intake question
Im trying to find the right intake fo rmy needs, ive tried multiple searchs but nothing is conclusive... Basicly im trying to remove the stock airbox and piping, but al of the intakes of looked at dont have the hookups for the Vaccum lines?? or the hosed that lead to the stock airbox.. what intakes actually come with those nipples?? For some reason rx7store.net dosent have good pics of there intake products.
Apexi, HKS, etc.. Most of them will have hookups for the BOV, CRV and airpump. The relief line for the airpump is the only one that won't have a place to attach:

That hose is the bypass air hose from the AIR CONTROL VALVE (ACV) that regulates the amount of secondary air injected into the Exhaust Ports and Catalytic converter. When air injection is required the ACV valve opens and the Air Pump (AP) is turned ON (buy the clutch engaging) when less air than the total output of the AP is required the ACV cycles rapidly open/closed and the extra air is vented out the bypass tube (this produces the mooing sound) Throttling the air this way is MUCH easier on the AP, pullies & belt than cycling the clutch rapidly to control the airflow. plugging that tube will cause extra loading on the airpump, pullies and belt, and excessive pressure on the ACV. Much the same effect as removing the BOV would have on the TURBO.
