Fabspeed’s high-flow sport headers are designed to retain full cabin heat functionality while unlocking noticeable performance gains. Thanks to a shorter exhaust gas path and smooth mandrel bends, these headers dramatically improve exhaust flow - boosting power, sharpening throttle response, and reducing turbo lag, with boost onset up to 1500 RPM earlier than stock. They also deliver a mild increase in volume, a more pronounced turbo spool sound, and a deeper, more aggressive exhaust tone.

Fabspeed’s high-performance intake system replaces the outdated, heavy steel factory airbox found on 930 and 964 Turbo (965) models - a design originally from the 1970s and '80s that traps heat like a Dutch oven and severely limits airflow. This factory setup bakes the intake air, reducing performance and efficiency. In contrast, Fabspeed’s Cold Air Intake is engineered to reduce weight and deliver significantly cooler, denser air directly to the engine - resulting in dyno-proven horsepower and torque gains.  

- Saves maintenance time, and weighs much less, for better handling and cooler engine temperatures.  
- Increases horsepower and torque by +17.5 HP and +26 ft-lbs. 
- Significant weight savings along with finally an uncluttered CLEAN to BE SEEN awesome engine bay.

FITMENT NOTE: After the initial heat cycle, be sure to retighten all exhaust bolts to OEM torque specs to ensure a proper, lasting seal.

NOTE: This system replaces the factory catalytic converter with a high-flow setup and is not MOT compliant, meaning it is intended for race and track use only and must not be used on public roads. If you are located outside the UK, please check your local laws and regulations to ensure compliance before installation.
