I bought an 04 WRX. I changed the stock intake system and put in a ram air intake with the stock air flow sensor. The car ran like crap. The idle was terrible and I had no acceleration. Everything else is stock on the car except the exhaust. I put the stock air intake on it and it ran smooth and strong. Any Ideas?
