Improving the performance on the 3.4L engine for the Porsche 981 Boxster | Cayman just got easier with the Agency Power upgraded throttle body kit.  The direct fuel injected engine sits just in front of the rear wheels giving the 981 amazing balance and handling.  However, this engine design provides challenges to doing bolt on modifications.  To improve vehicle performance, Agency Power has designed a kit that utilizes the OEM Porsche 997 GT3 82mm throttle body. 

The larger diameter throttle body allows for more air to go into sucked into the engine.  As the old school formula goes, the more air, the more power.  Air going into the throttle body from the intake side is more important than what is behind the throttle body.  Because the Porsche engine works off of pulses, there is no reason on this 3.4L engine to change the plenum.  The factory plenum has enough flow and the only reason to change it out would be installation convenience for other products.  The GT3 Porsche throttle body has a larger bolt pattern which will not bolt up to the stock plenum.  So Agency Power has engineered a CNC machined adapter which allows the use of the stock plenum to the larger throttle body.  The adapter has been precision machined out of 6061 aluminum and features an anodized finish with the Agency Power logo.  Its unique keyed fitment allows for easy installation on the vehicle.  With tight engine space and larger diameter parts, the factory rubber intake hose nor a hard aluminum pipe will work.  To offer the best air flow and easiest installation, Agency Power has designed this silicone intake piece.  The 3 ply silicone hose clamps securely to the throttle body and intake pipes.  

The upgrade kit is a direct plug and play and includes the necessary adapters, clamps, silicone hoses and throttle body to fit to your car.  As tested on a Porsche 981 Cayman S, the throttle body kit added a peak gain of 20HP at 6435 rpm where it averaged about a 10-15hp gain from 5000 rpm to redline.  Torque maintained an average of 10 ft/lbs from 5000 rpm to redline.  Tuning is not required, though as tested with a VR Tuned ECU Flash, performance is maximized throughout the entire RPM range.
