the silver thing mounted on the LIM

I think it is the ACR, not really sure what it does. I took mine off and blocked it off. I am sure it has some thing to do with emissions.

yea, i want to keep my emissions **** on, but i dont think that really does a WHOLE lot, seeing as it just takes fresh air in from the air box directly into the LIM (from what i can logically see)...the only thing is, if i take it out and block it off, will the stock ecu give me check engine lights?

If you are running the stock ecu you have to leave it in. It made my friends car like ass without it.

It's the air control valve. It decides where to send the air from your air pump.

okay, so i'll be leaving it in... thanx for helpin me out with that one!
