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???
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.
