If it is a "good thing", why doesn't do something more positive? Increasing surface area or changing the volume upwards on intake systems does not always yield anything positive, and quite often makes things worse.

To properly gauge the impact of intake modifications, they need to be first tested on a flow bench to determine the amount of and direction of the change, and then confirmed in terms of engine volumetric efficiency on a fully instrumented dyno. And quite often, making things flow better in the intake then mandates modifications to the cylinder heads and cams to actually take advantage of the flow improvement's.

These engines are a system; making a change over here often yields nothing without a lot of other changes as well. That is what engine development is all about, and anyone that has done it will tell you bigger is not always better.........
