"  Well, that didn&amp;#039;t take long. The seventh generation of Porsche 911 is barely out of the blocks and it&amp;#039;s already getting a performance upgrade, courtesy of the Porsche Exclusive &amp;quot;Powerkit&amp;quot; for the 2013 911 Carrera S. With this engine upgrade output of the 3.8-liter 6-cylinder boxer engine climbs from 400 hp to 430 hp. Coupled with the PDK transmission in Sport Plus mode, Porsche estimates the 911 Carrera S Coupe accelerates from 0 to 60 mph in 3.9 seconds while top speed has increased to 191 mph. As an added bonus, Porsche says this extra power and performance does not adversely affect fuel economy.  The extra 30 horsepower has come via several tweaks, including a redesign of the cylinder heads and camshaft profiles, along with modifications made to the electronic engine management system. The &amp;quot;Powerkit&amp;quot; includes a variable resonance intake system design with six air flaps and an additional resonance flap. Porschephiles will spot an additional center radiator, special sports exhaust, and Sport Chrono package with dynamic engine mounts. To impress onlookers when opening the engine cover, Porsche has kindly included a titanium-colored engine cover with carbon inlays. The Powerkit will be available in the U.S. this fall.  Porsche Exclusive is also offering some eye candy, such as a lower front apron and fixed rear &amp;quot;ducktail&amp;quot; spoiler. Choose the Aerokit Cup and you&amp;#039;ll get an additional fixed rear wing (over the standard rear spoiler) and that new front apron with its extra air intakes. Is that still not enough? There are unique cabin trim pieces finished in brushed aluminum or carbon-fiber for anyone who can&amp;#039;t stop ticking boxes on the options list.
