EVO seems to be a popular induction kit. I've seen them run about $400. I've heard that it's hard to wrestle the old box out and the new filter into the limited space of the boxster. It looks pretty cramped back there from the pics that I've seen. I've also heard the EVO fits very tightly in place and its a real stretch to fit it over the intake manifold. Many people have praised the EVO system once it is finally installed though. I still think the fabspeed package looks good which gives an extra 34hp(claimed) to the rear wheels. Now that is power that you can feel! If it is true then a 300hp boxster S is at anyone's finger tips. Plus, the engine stays N/A.
