Product Information
Product Information
Engine Throttle Console Bearing Bush.
The Porsche Engine Throttle Console Bearing Bush is a genuine OEM component that ensures smooth and precise operation of your throttle linkage system. Installed within the throttle console or bracket, this bearing bush provides a friction-reducing pivot point for the throttle rod, preventing metal-on-metal contact and maintaining accurate alignment.
Sold Each.
x2 Required Per Car.

Fits:
  • Porsche 911 1984-1986 3.2L
  • Porsche 911 1987-1989 3.2L G50
  • Porsche 964 (911) TURBO 3.3L 1991-93
  • Porsche 964 (911) TURBO 3.6L 1991-93

What This Product Does:

  • Acts as a bearing surface / buffer between the throttle linkage rod and the bracket or console, allowing smooth pivoting / sliding motion.
  • Prevents direct metal-on-metal contact, reduces friction, and helps maintain alignment of the throttle linkage.
  • Helps maintain throttle precision: by keeping the linkage centered and supported, pedal input translates cleanly to throttle motion.
  • Absorbs small amounts of vibration / wear to protect surrounding parts.

Symptoms Of A Worn / Failing Throttle Bush:
  • Loose / sloppy throttle / accelerator pedal feel — play or lag before the throttle responds.
  • Inconsistent or delayed throttle response as the linkage “wanders” slightly before engaging.
  • Noise — clicking, squeaking, or clunking from the linkage area.
  • Visible wear or grooving on the throttle rod or bracket where the bush fits.
  • Binding or sticking if the linkage is slightly misaligned due to the worn bushing.

Why Replacement Matters:
  • Restores crisp throttle control and responsiveness, which is especially important in performance or spirited driving.
  • Protects the throttle rod, bracket, and linkage from extra wear caused by misalignment or metal contact.
  • Eliminates unwanted noise, slack, or erratic behavior in the throttle linkage.
  • Maintains correct throttle geometry and alignment — a worn bush can allow slight deviation that impacts pedal feel.

Throttle Return Spring. Porsche 911 1970-83 - 91111016502, 91111016501

Throttle Return Spring. Porsche 911 1970-83
Special Order item

Product Information
Product Information
Throttle Return Spring.
The Porsche Throttle Return Spring is a genuine OEM component designed to ensure reliable throttle response and safe operation. Installed in the throttle linkage assembly, this spring provides the tension needed to return the throttle plate to the closed position whenever the accelerator is released.

Fits:
  • Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)
  • Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
  • Porsche 911 1978-1983 3.0L / SC

What This Product Does:

  • The Throttle Return Spring provides the force that pulls the throttle (or control linkage) back to its idle / closed position when the accelerator is released.
  • In a fuel injection or mixture control setup, such a spring keeps tension on the throttle and ensures the throttle plate or mixture valve returns reliably, preventing it from staying open or partially open.
  • It helps maintain consistent throttle behavior, ensures smooth transitions off-throttle, and prevents unwanted throttle creep.

Symptoms Of A Worn / Broken Return Spring:
  • The throttle may not return fully: the engine feels like it wants to hold higher RPM or won’t settle at idle.
  • Delayed or sluggish engine deceleration when releasing the accelerator.
  • Inconsistent or unstable idle, perhaps with the throttle slightly open.
  • A “creep” effect — the engine seems to maintain higher revs when it should drop.
  • Visible damage to the spring (stretched, corroded, weakened) or the spring detached from its linkage.

Why Replacement Matters:
  • Ensures safe, predictable throttle behavior — a faulty return spring can lead to unsafe throttle response or lag in returning to idle.
  • Prevents throttle slop or hang — keeping the linkage under correct tension improves drivability and control.
  • Protects against accelerator-related faults — if the throttle doesn’t retract cleanly, it may stress other linkage parts or cause erratic engine behavior.
  • It’s a relatively inexpensive part that can avoid more severe problems with the throttle / injection linkage over time.

About Throttle Control Parts

High-Quality Throttle Control Parts for Smooth, Accurate & Responsive Engine Performance

Throttle control parts—such as throttle bodies, actuators, linkages and position sensors—play a critical role in managing airflow into the engine. By regulating how much air enters the intake system, these components directly influence acceleration, idle stability, fuel delivery and overall drivability. Modern electronic throttle systems rely on precise signals between the accelerator pedal, throttle body and engine management unit, while older mechanical systems depend on accurate linkage movement and tension.

Whether restoring performance, addressing drivability issues or upgrading intake responsiveness, high-quality throttle control components are essential for maintaining smooth, predictable engine behaviour.

What Throttle Control Parts Do

Throttle control parts ensure proper airflow and communication within the engine’s intake and injection system by:

  • Regulating airflow into the engine based on driver input
  • Maintaining smooth acceleration through precise throttle plate movement
  • Providing accurate feedback via throttle position sensors
  • Supporting stable idle speed under varying load conditions
  • Integrating with the ECU for balanced fuel-air ratios
  • Enhancing responsiveness, especially in performance-tuned engines

A correctly functioning throttle system allows the engine to deliver predictable power, quick throttle response and efficient combustion.

Why Throttle Control Systems Commonly Fail

Throttle components operate in a hot, contaminated environment and are subject to mechanical and electrical stress. Failure can occur for several reasons:

  • Carbon buildup on the throttle plate causing sticky or uneven movement
  • Worn throttle actuators leading to slow or inconsistent response
  • Damaged linkages or cables on mechanical systems
  • Electrical faults in electronic throttle modules or sensors
  • Vacuum leaks affecting airflow measurement and idle stability
  • Moisture intrusion, causing corrosion or connector failure
  • General age-related wear reducing sensitivity or accuracy

Symptoms include erratic idle, reduced power, delayed throttle response, limp-home mode activation or engine hesitation.

Why You Should Replace Faulty Throttle Control Parts

Swapping failing components with precision-engineered alternatives designed to meet original performance standards provides significant reliability and drivability benefits.

Key advantages include:

  • Restored throttle responsiveness and smooth acceleration
  • More accurate airflow control and improved engine efficiency
  • Prevention of idle instability and stalling
  • Faster ECU communication for modern electronic throttle systems
  • Reduced fuel consumption thanks to accurate air-fuel metering
  • Better compatibility with performance upgrades and remaps
  • Improved reliability for both modern and classic Porsche models

A refreshed throttle system ensures consistent performance and enhances driver confidence.
