IPD 74mm Plenum for 987.2 Porsche Boxster & Cayman [87474-2.9]

IPD 74mm Plenum for 987.2 Porsche Boxster & Cayman [87474-2.9]

The 987.2 Boxster and Cayman 2.9L IPD Plenum is a direct bolt-on upgrade that uses all existing factory hardware, including the original 74mm throttle body. Its enhanced intake design promotes smoother, less turbulent airflow with higher intake velocity, resulting in impressive power and torque gains. This IPD Plenum provides additional horsepower and, unlike previous naturally aspirated models that emphasized mid-range gains, maintains a factory-like power curve while delivering significantly stronger output from the mid-range to redline. Power and torque increases begin in the mid-range and consistently surpass factory outputs up to redline, with no power loss in the lower RPMs.
