Straight answer on intake hoses

Post by ericem »

Looking for size of hose from stock intake to wrx IC. Is it 2.75 or 3"? What about the 90* hose for the td04 is that one 3" or 2.75" ? Does anyone recall the size of the hose for the PCV that goes from the block to the f-pipe? I am searching but I feel confused and I don't want to order a bunch of parts that don't work!

I went out to my garage and measured my td04L sitting there. OD diameter of tdo4 outlet is 2.0", same as inlet pipe going into wrx IC. Wrx IC outlet to throttle body is 2.75" OD.
