sorry for misscommunication, this one has its own C&C machined housing for MAF (i dont know if that better than the plastic EVO one or not) and does require to take everythign off just like the EVO, its the same thing, but does not have a shield, so i dont really know what you saw or where you saw it.
this is the one that i have:
and this is what it looks like installed:
this is the
site that i got that pic
this is the gist that they say, with real dyno data, so...
" A frequent poster on the Boxster Racing Board installed one and did before/after dyno tests. It resulted in an impressive 14 horsepower and 12 lbs/ft torque gain. This was on top of power he'd already gained from installing a "Danske" muffler"
and
"Another Boxster Racing Board poster also performed dyno tests after installing a Powerflow intake. He reported a smaller 6 hp improvement on his website. Hard to say which is more representative, but it certainly does look like the Powerflow intake helps to some degree."
so i guess it will do something for power, but add the sound. we shall see
