The only way to end speculation is to take some measurements. "My car feels faster" or "My car seems to rev easier" are not measurements. Invest a little more in your invention and take your car to a rolling road dyno and run your car with the original airbox and your new airbox. Make no other changes between runs. A sample of just one car isn't statistically significant, especially if the gains are modest, but it is better than anecdotal observations.

I sugest you wait a couple of weeks until my first buyers tell you all about it before you speculate too much.
