Lower underbody panel with vent.  By adding this panel and removing a hard foam stopper (currently in place on your vehicle), this adds additional air flow to the engine compartment.  Through rigorous high-tempature track sessions on our 718 Project Car,  we were having heat-soak issues with the turbo.  More air flow seems to be the cure.  This is not a factory recommended upgrade, just one of the measures which we have used to improve track performance.  This can be  used on all 2017-2024 718 Boxster or Cayman models.  This has also been used on 991.2 GT3 models.

Oversize packaging.

These aggressive underbody ducts are standard on "RS" models. These will have minimal or no impact during your daily commute, but are effective at track speeds. Consult a race shop, additional front & rear body spoilers could be necessary to balance out upgraded aerodynamic components. Modifications are required for fitment, install and use at your own risk.
