				Added HP?
			 
 
			Wonder how Porsche added 20 or so HP and a little torque from the 2001 model I have to the 2005? Still 2.7 liters. Anybody know?Similar, is there anything much to be gained from some of the aftermarket air intakes/filters? They claim improved breathing but how do you know -
 just wondering - coulda used a little more torque on the straights (no razz from the s guys please)
