THESE BUMP STICKS ADD MORE POWER TO YOUR STI

These are the GSC Power-Division S1 Camshafts. These camshafts offer a great bump in power throughout the RPM range while maximizing the potential of your factory or upgraded turbocharger. Camshafts will add more trap speed for those of you in the 1/4 mile and will improve the overall engine response for weekend track events. Although the S1 camshafts aren't too aggressive in terms of having a longer duration, they will require upgraded valve springs and a tune to properly employ this upgrade.
