Genuine Porsche Throttle Return Spring for CIS Fuel Injection

The Genuine Porsche Throttle Return Spring is an OEM replacement part for CIS (Continuous Injection System, also called K-Jetronic) fuel injection systems. It pulls the throttle linkage back to the idle position when you release the accelerator pedal. This is also called a throttle linkage return spring or throttle spring.

Key Features:

• Genuine Porsche original equipment part
• Made for CIS mechanical fuel injection throttle linkages
• Returns the throttle to idle for smooth, predictable throttle response
• Replaces worn, weak, or fatigued springs that can cause a slow or sticking throttle return
• Built to factory specifications for correct fit and spring tension

A fresh throttle return spring helps keep idle behavior and pedal feel consistent. Choosing a genuine Porsche part means the spring matches the original design. Select the correct part number from the variants listed on this page.
