So can someone explain the physics that is occurring behind the Stillen intake? From my understanding longer tubes cause a reduced pressure within the tube due to increased drag. Reduced pressure typically means less power due to getting less air into the manifold. The only thing that I can account for in the power gain is colder air, reduced turbulence from the smooth surface of the piping, larger air filter. I think I am missing a key factor. Discuss.
