987.2 Boxster Non-S 2.9L 74mm IPD Plenum ('09-'12) | Part #87474-2.9

The specifically designed 987.2 Boxster Non-S 2.9L Plenum is a direct bolt-on upgrade that replaces the factory plenum and utilizes all pre-existing factory hardware including the OE factory throttle body.

The improved IPD intake design allows for smoother, less turbulent and more efficient air flow with higher velocity air intake speed creating impressive power and torque gains.

The superior design of the IPD Plenum provides an additional horsepower. Unlike previous naturally aspirated IPD plenums that delivered stronger gains in the mid range, the new IPD Plenums deliver a similar shaped power curve as the factory but are considerably stronger from the mid range to redline.

Installation of the IPD 2.9L Plenum is relatively straight forward and can be installed by mechanically inclined DIY customers although IPD strongly recommends installation be performed by a trained and qualified Porsche technician.

NOTE: All IPD products are designed and manufactured to deliver increased performance for Porsches that are strictly driven on public roadways. All IPD Plenums come with a full 2 year manufacturer’s warranty to the original purchaser that guarantees all IPD product will be free of any manufacturing defects or cause of any issues or problems related to the vehicle’s engine. All IPD Plenum warranties are expressly voided if installed and driven off-road or on race tracks.
