Today I bought and installed a Blitz short air intake system for my '03 WRX. It's my first modification and my first problem. After an hour of driving, the CEL came on, and is on all the time when the car is running. I like the air intake system, it sounds cool, but I've noticed a loss of torque and doesn't accellerate as quickly and smoothly as before.
Has anyone else had this problem? How can I fix it? Am I better off with the stock box?
