Guess not many have see this thing or played with it. What it looks like to me is that is takes out the hight and interference the incoming air encounters as it passes around the air horn to get to the secondaries. Using a stubstack, I think the air to the secondaries would smooth out and speed up, meaning more air, and a possible lean condition, which is a good thing because if the engine is asking for more fuel it wants to go faster . K&N are pretty good at the intake game , the air filters sure do show improvements, for 20 bucks I think I am willing to give it a try.............. anyway that is the plan should be fun finding out. All comments welcomed BTW
