Easy, cause on the end of the pipe is a kn filter element. Arent all filter elements from kn the same? Same oil? Same warranty? Ive purchased both drop ins and cai kits and both I notice an improvement in drivability from the butt dyno.I never noticed any increase in mpg. Thats ok, Ill take that. If I see nothing Ill be the first one to return it.
I return several items a month I purchase because it didnt perform as expected, failed or I didnt like it.

What we really need is a prius or some car that has independent control of the engine, a set route about 20 miles to set cruse control and just steer the car on to really give an updated test. Then test a stock, drop in, dirty and a cai. Interesting the "performance" filter caused a drop in mercury and most hybrids have a delayed closing of the intake valve to lessen pumping losses to increase efficiency, ie lower vacuum psi.
