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.
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.
