Intake Plenum For Porsche 996 Carrera(3.4L) (1999-2004) Models.

It can be challenging to find significant power gains for the naturally aspirated 3.4L Carrera, but the IPD Plenum is one of the most effective aftermarket modifications available. This simple, direct bolt-on performance upgrade replaces the factory plastic air distributor with IPD’s patented aluminum “Y” style Plenum.

The superior and more efficient design of the IPD Plenum delivers impressive gains of 25 horsepower and 22 foot-pounds of torque. These improvements are most noticeable in the mid-range, where they are most enjoyed, but performance is enhanced throughout the entire rev range. The added mid-range power creates a more linear power curve, helping to minimize the typical power dip found in the factory curve.

Key Features:

• Performance Gains: Delivers an impressive 25 horsepower and 22 ft-lbs of torque, with a focus on the mid-range.

• Design: Replaces the factory plastic air distributor with a patented aluminum “Y” style Plenum.

• Power Curve: Creates a more linear power curve by reducing the factory power dip.

• Installation: Direct bolt-on R&R (remove and reinstall) procedure.

• DIY-Friendly: Installation is relatively straightforward for mechanically inclined customers, though IPD strongly recommends professional installation by a qualified Porsche technician
