Engineered for precise fitment and reliable performance, this kit provides a complete solution for restoring accurate throttle response and airflow control.
What the Throttle Body Does
The throttle body is a key component of the engine intake system. It regulates the amount of air entering the engine based on accelerator pedal input. In modern Porsche engines, the throttle body is electronically controlled, working in conjunction with the engine control unit to optimise performance, fuel efficiency and emissions.
The throttle body:
- Controls engine air intake
- Regulates idle speed
- Supports smooth acceleration
- Maintains correct air-fuel mixture
- Ensures stable engine performance under load
The throttle body seal prevents air leaks between the throttle housing and intake manifold, while the mounting bolts secure the unit with correct clamping force.
Why Throttle Bodies Fail
Over time, throttle bodies can fail due to:
- Carbon and oil residue build-up
- Internal electronic actuator wear
- Motor or position sensor failure
- Heat cycling and vibration
- High mileage wear
A faulty throttle body can disrupt airflow and cause inaccurate throttle position readings.
Common symptoms include:
- Rough idle Hesitation during acceleration
- Surging or inconsistent throttle response
- Check engine light
- Throttle actuator fault codes
- Limp mode activation
If the seal deteriorates or bolts are reused incorrectly, air leaks can also cause lean mixture faults and unstable engine behaviour.
Why You May Need a Complete Throttle Body Kit
Replacing the throttle body along with a new seal and mounting bolts ensures a complete and secure repair. Reusing old seals can result in air leaks, and reusing old bolts may compromise clamping force.
This kit is recommended for:
- Vehicles displaying throttle position fault codes
- Turbocharged engines experiencing hesitation or power loss
- High mileage preventative maintenance
- Intake manifold service work
- Carbon cleaning or performance refresh projects
Installing a new throttle body restores precise airflow control, smooth throttle response and reliable engine performance.
At Design911, we supply high-quality throttle body kits designed to meet OEM performance standards. Each component is engineered for durability under the high airflow and boost conditions found in Porsche Turbo models.
Replacing a worn throttle body improves drivability, responsiveness and overall engine efficiency.
