ok, lastnight I put a cone style filter on my 87 SE replacing the factory air box....after I did this I have a hose that is not hooked up anywhere. Its the big hose coming off the thing beside the EGR valve. It has a vacume when when car is on, and the car will run with it un hooked....so what I did was plugged it with a cork and it run much smoother. Should I have plugged this? What have you guys done with this hose when you have put a cone filter on your car? Can I just put a breather filter on the end of the fitting? Thanks.

That hose is the AIV hose. It injects air into the exhuast stream. What I did with mine was cut the hose down and added a breather to the end of it. Plugging it won't hurt it, but it may effect your emission a little, though I don't think it's anything major.

ok thanks...I have run it with it pluged and un pluged and there does not seem to be that much of a difference other than with it plugged it run a little quieter...but I have already bought a little breather filter(K&N style) and I will put it on tonight...I figured it was nothing big...on a side note I did get the cone filter in and it does look much better than the stock air assembly, though it is not in the best location....RIGHT BEHIND THE BATTERY!!hahahah. Oh, and it does not make a growling noise that my other intakes have made under full throttle ( guess I need a mid pipe). Are there any suggestions for a mid pipe? I know about the piggie racing set up but has anyone tried any other set up that utlizes a mid pipe? Thanks.
