  • 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.

  • Straightens and speeds up air flow through your carburetor
  • Available for most popular carburetors
  • Better fuel metering

    Rated 5 out of 5 by from This Stubstack actually does work on my Holly carb I thought that I might just be wasting money on yet another gimmick. But, this thing actually does work. I had been having trouble getting my cowl induction hood vent door to open on my 71 El Camino. It is supposed to open when the vacuum decreases at high RPM. This Stubstack got rid of the turbulence and increased the air flow (and thus decreased the vacuum at high RPM) . I now have excellent response from my cowl induction hood, the way it is supposed to function. Now, I'm going to see if I can go a size bigger on my main jets. But, I'm not yet sure about that.
