For those of you who love naturally aspirated power for its responsive nature and lightweight feel, but want to take it up to the next level of performance, we have developed this Stage 3 kit just for you. This kit utilizes a head modification and special port timing changes to increase the combustion efficiency of this engine and provide incredible throttle response and more top end power. These modifications are used in conjunction with the ever popular SLP single pipe, Powder Valve™ Intake Kit and Power Shift™ Clutch Kit. This kit is currently only available for elevations 5000’ and higher. Please contact us for more information.
