Gains of 30-55 WHP (depending on turbo) have been seen by simply bolting the S1 cams in.
    • Designed for a rev range of 3000-7500 RPMs
    • These cams work well on the stock valve springs with lower boost and RPM goals

    **If using aftermarket cam gears (especially AEM) check the bolt length. Some cam gears are too thick for the OEM bolt on the billet cams, a 40mm underhead length bolt may be necessary in this case**
