I have a Volant Mass Air Intake and a Volant dual exhaust. After each upgrade, I noticed my check engine light would come on and off at random times. Didn't seem to effect performance. Adding this mod smoothed out the idle and made a world of difference when getting on the gas. Wish I would have made this change when I added the air intake. Best mod yet for he money!!!
