If it has an SAI (I think this is what you meant by SRI) there will be 2 hoses connected to the air intake. If there is only 1 then no SAI. I am pretty sure MLue said he didn't have one so I thought the SAI is just a US emissions thing. If you only have 1 hose at the air intake tube it goes to the oil filter breather. This lets air into the crankcase. PCV let's air out. The circle of life.I guess I can run the return to the piping just before the intake as the biggest port on IE's intake is 1/4. Would I still need a breather on the can if it's a closed system just incase theres a pressure build up?
My car is Canadian and has an SRI system. I'm near positive it does at least, isnt that where the hose before the intake goes???
