That post makes no sense to me!

Any power change at low rpms would be minimal at best and should "only" be an increase, not a decrease as he suggests. At low rpms, there is no additional or increased airflow from an aftermarket intake when compared to a stock intake. Therefore there should not be any difference in performance. An increase in performance with an aftermarket intake will be seen when the aftermarket intake canactually increase the airflow over that of a stock intake. At that point more air is delivered to the engine and more air equates to more power from that particular rpm point and onward (higher) under WOT conditions.

The only other scenarios involved in changing from one intake to another would be a temperature change due to placement and possibly negative eddy currents that may be set up due to the surfaces and curvatures of the intake's construction.

I believe the decreased performance is all in his mind.

PS - If it was an exhaust system he was discussing, it could be a different story!

It appears there are some unhappy ECIS customers. Interesting stuff.
