I put a CAI in my 88 stang (n/a). I have a question about the old air filter box, do i take that completely out, and if i do, what about the hose that connects to the exhaust. What do i do with that? Can someone please help me?
The hole in the exhaust is actually just in the heat shield around the header. You can take the hose off without fear of anything leaking. Just make sure you plug the small rubber vacuum lines going into the top of the air box.
Theres actually only one Vacuum line to worry about. When I did my CAI . I just screwed a screw in the line. The other line actually just connects the top of the stock air filter box to the bottom of the box. I completely ditched my stock stuff.
Thanks for all the input. I have another question, but it doesn't relate to the CAI. I am wanting to take the awesome luggage rack of the trunk of my car, but it is held on by rivets. Does anyone know how to do this? I should just post a new thread, but i will wait for responses first.
and the hot air intake tube was intended to keep the intake charge at a proper temperature for good fuel atomization during cold weather operation. It obviously would not help with a cold start if no hot exhaust had been produced yet.
I think that the tube connecting the stock airbox to the exhaust manifold is just to help your car warm up on cold days once it has been started. Instead of just taking in the cold air from outside and burning it on cold mornings, it takes a little bit of warm air from the exhaust and it supposed to help it to warm up. However, I dont really think it'll make that much of a difference. Just ditch it. I dont have mine on anymore because the hose ripped, and mine seems to work just fine.
there is 1 hose that is the vaccuum supply for the door in the airbox that meters in warm air as necessary. Remove it and plug its connection at the vaccuum manifold on the firewall. If it is left open you have a vaccuum leak which lets air into the engine.
