Product Description

Unlock the hidden performance potential of your Porsche 718 4.0L flat-six with the COBB Tuning Accessport V3. Designed specifically for the naturally aspirated 4.0L engines found in the 718 Cayman GTS 4.0, Cayman GT4, and Spyder, the Accessport replaces conservative factory ECU calibrations with optimized COBB performance maps designed to improve horsepower, torque, throttle response, and overall drivability. Beyond tuning, the Accessport provides real-time monitoring of critical engine parameters, onboard diagnostics, and the ability to easily switch between calibrations for different driving environments or modifications. With support for future bolt-on upgrades, the Accessport becomes the foundation for building and fine-tuning your ultimate Porsche 718.
