Best option for me...read...
Okay hear me out. I've owned 3 WRX's over 16 years. My newest car of 5 years is a 2018 WRX. I bought the Process West Intercooler w/ Piping. After rebuilding my car and going stage 2 the PW turbo/recirc/charge pipe kept popping off at the turbo flange. 6 times in the last 5 months. Also the charge pipe was pushing really hard against the radiator coolant hose where it meets the motor. I replaced hose clamps, removed and readjusted the CP...nothing helped. I bought this CP kit from Grimmspeed and I really like that the silicone hose connects almost at the top of the engine (easy access) and does not rub against the the radiator hose or anywhere at all. So take it from me, I feel like i've wasted money....do it right...go Grimmspeed!
