I have just aqquired a top mounted IC from a 2nd gen RX7 and was wondering what the other 2 pipes are for, not the airflow pipes, it seems like they are coolant pipes of some sort. Any insight as to what they are? Thanks

they aren't coolant pipes, hooking a coolant line up to them would be pretty bad....I'm sure where they go off the top of my head but tommorow I will look and if I can get my digital camera back from my brother I'll take pictures for you... see ya

They're vacuum lines, but I don't know what they are used for. I tried to start mine after I forgot to re-attach them, and the car died right away.

I believe they are vacuum lines to control the blow off valve, not completly positive on that though

They're for the fast idle when you start the motor cold.
