So I'm looking at this:

from Evo http://www.evoms.com/porsche%20ec%20art%20test.htm click Boxster then Intake.

They claim 8-10whp and tested in on a 00 S model and gained 11 hp. Dyno Chart

The design seems solid with using the stock pipe at the end to fit perfectly, smooth polyurethane piping to the MAF with a billet housing that moves the MAF sensor over and a open cone filter with a heat shield. Honestly I can't see how this won't make power over the stock air box with all the stupid resonance chambers, wrinkled piping and limited filter element size.

They sell for $379 which is a bit steep for an intake but considering the CNC maf housing I know that’s a bit of work for setup and making them all so that’s worth some money plus all the R&D testing it etc.. it seems pretty good.

Anybody else have one or know anything about it? I know we all say stick with the stock air box, but there are gains to be made over a stock system that’s designed to keep noise down to a certain decibel limit. That’s a compromise and when you compromise design for noise you trade off HP every time.
