IPD Plenum 957 Cayenne Turbo 07' -

More Air = More Power!!_x000B__x000B_IPD Plenum?s patented, cast aluminum ?Y? style plenum increases horsepower and torque by optimizing airflow into the intake manifold. _x000B__x000B_The factory plastic ?T? style intake creates airflow turbulence, which deprives the motor of air, robbing Hp and torque. IPDs ?Y? style plenum smoothly channels the airflow towards the left and right cylinder banks. The engine receives a larger mass of air at a higher velocity, which equates to increases in Hp and torque across the entire rev range. The end result is improved acceleration and increased boost response (on turbo vehicles)._x000B__x000B_IPD Plenum?s provide dyno proven results and are a simple and cost effective way to increase power. _x000B__x000B_Want more power? We suggest combining the IPD Plenum with a larger throttle body (for vehicles that apply). _x000B__x000B_Note: To be used with factory 82 mm throttle body. Contains everything necessary for installation. Installation instructions included. Porsche DME/ECU?s automatically adapt to the increase of air within 5 to 50 miles of installation. Resetting the DME/ECU is not necessary and additional software is not mandatory._x000B__x000B_
