K&N Stubstacks are a very simple way to bolt on more HP for your carbureted engine. Stubstacks smooth out the rough casting and air transition turbulence common on most carburetors. By smoothing out the transition from air cleaner to venturi you allow for not only a higher flow rate, but better metering accuracy which leads to better throttle response and more power throughout the throttle curve. Applications listed below.
