I'm installing a custom CAI for my car. What do I do if I want to retain the smog pump? (Which I do, so please, no "just throw it out" suggestions.)

I have seen one CAI with the stock smog pump hose and some goofy looking K&N filter on the end. Is that necessary? Can I just leave it with an open hose in the engine bay? What are my other options or retaining it?

Put a small $3 breather filter on the hose going into the air pump. When I didn't have one the car would stall sometimes. Once I put one on, all was well.

Well, alot of people run with the air pump sucking unfiltered air for years and have no problems. Myself, I would get one of these..

So until that filter arrives from Rotary Performance should I run open hose or open air pump? Basically should I leave the hose on or not? Does it matter?

take the hose off, its not going to make a difference.

 

you just want to keep any debris from entering the air pump, it's a pump designed to move fluid - air... solid debris can break it.

 

Thats what I did, went to autozone, bought a cheap one and straped it on.

 

Plumb the airpump into the CAI as in the stock application...
