A Quick Look at Porsche

Porsche information on this page is based on details supplied by the manufacturer or distributor, plus any OE references provided with the parts.

Choosing the Right Fit for Your Porsche

Where Porsche is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side/position, and connector type where relevant.

  • Typical reasons people replace these parts include maintaining originality, keeping factory specification, and choosing the latest genuine revisions for peace of mind.
  • Common real-world issues behind many Porsche repairs are age and mileage: oil leaks, cooling system fatigue, brake and suspension wear, corrosion and electrical faults from moisture or heat cycling.
  • Before ordering, confirm part numbers against VIN or option/PR codes, especially for safety‑critical or complex components.
  • When upgrading, decide whether you want pure originality or performance changes, as some aftermarket options may suit specific goals better than genuine.
  • For bigger jobs, replace related seals, hardware and consumables at the same time to avoid repeat labour and compatibility issues.
  • Where available, follow the manufacturer’s fitting and bedding‑in guidance to get the best performance and longevity.

Browse by Category

If you already know the area you are working on, start with the category and then filter by Porsche model. Where real-world symptoms and typical reasons to replace are provided, use them to keep the wording grounded.

Brakes — Brake components are renewed to restore stopping performance, address wear or upgrade a Porsche for fast road or track use. Common symptoms include: Common symptoms include vibration under braking, increased stopping distances, squealing, pulling to one side, warning lights and visible wear to discs and pads.

  • Check whether the parts are OE-equivalent replacements or performance upgrades and match this to how the Porsche is used.
  • Follow any recommended bedding-in procedure and consider replacing discs, pads, sensors and fitting hardware together where advised.

Clothing & Gifts — Porsche-themed clothing and gifts let owners and enthusiasts show their passion off the road, or make ideal presents for fans of the marque. Common symptoms include: Items may become worn, faded, damaged or go out of style, prompting replacement with newer designs.

  • Review available size, colour and material details to help choose the right item and ensure it matches how it will be used.
  • Check any care or washing guidance so garments and accessories keep their appearance for longer.

Lifestyle — To explore different Porsche-inspired lifestyle products or gift ideas. Common symptoms include: General wear from handling or display.

  • Confirm whether items are official Porsche lifestyle products or from trusted partner brands where stated.
  • Consider who the item is for and how it will be used day to day to select the most suitable style or product type.

Keyring — To choose a different design, material or model theme. Common symptoms include: Scratches, worn finishes or loose fittings.

  • Keyrings make simple, practical Porsche-themed gifts and can be matched to specific models or heritage designs where available.
  • If a keyring shows damage or looseness, replace it to avoid losing keys or further wear to finishes.

Size chart — The size chart acts as a practical reference tool for all apparel purchases. Common symptoms include:

Manufactured to match the fit, feel and function of the original part, this switch restores smooth electrical operation and integrates seamlessly with the Porsche interior. It is a direct-fit component for vehicles requiring part number 99761315105A05.

What the Passenger’s Side Window Switch Does

This essential electrical component:

  • Controls the driver’s side window with single-touch or manual inputs
  • Provides additional passenger window control (model dependent)
  • Sends precise electrical signals to the window motor and control module
  • Ensures fast, responsive up/down movement
  • Supports comfort and security systems, including anti-pinch protection

Without a functional switch, electric windows may become slow, erratic or completely inoperable.

Why Window Switches Fail

Common reasons include:

  • Frequent use, causing internal contact wear
  • Moisture ingress from open windows or weather exposure
  • Dust and debris accumulation inside the switch mechanism
  • Electrical contact oxidation, reducing signal reliability
  • Broken internal springs or plastic tabs due to age
  • General wear from daily driving

Symptoms often include sticking buttons, no response, intermittent function or windows moving only in one direction.

Why You Should Replace a Faulty Window Switch

A new switch restores:

  • Consistent, responsive window operation
  • Proper driver control over all window functions
  • Improved cabin comfort and ventilation
  • Reliable operation of safety systems
  • A clean, modern look inside the door panel
  • Dependable electrical integration with the Porsche control modules

Replacing a failing switch prevents further strain on the window motor or wiring.

Over time, the pivot lever can wear, develop play or even crack due to repeated load cycles, heat exposure, or deterioration of the internal bushings. When worn, it can cause vague shifting, missed gear engagement, excessive shifter movement, or a complete inability to select gears. Replacing the pivot lever restores the original crisp, mechanical gear feel Porsche drivers expect.

What the Gear Change Cable Pivot Lever Does

This component:

  • Transfers movement from the shift cables to the gearbox selector arm
  • Ensures accurate gear positioning and engagement
  • Maintains tension and alignment within the shift linkage
  • Provides a stable pivot point for smooth shifting
  • Improves driving feel by reducing slack and friction

It’s an essential part of the Porsche mid-engine manual transmission system.

Why Gear Change Cable Pivot Levers Fail

Common causes of failure include:

  • Wear of pivot bushings, leading to excess play
  • Heat and vibration fatigue, causing cracking or deformation
  • Corrosion, especially in climates with moisture or salt exposure
  • Increased friction, resulting in stiff or inconsistent shifting
  • High-performance driving, which accelerates wear
  • Aging plastic or composite materials, causing brittleness

Failure symptoms include sloppy gear engagement, resistance when shifting, noise from the shift linkage or total loss of gear selection.

 Why This Part Should Be Replaced

Replacing the pivot lever provides:

  • Restored factory-tight shift feel
  • More precise and confident gear engagement
  • Elimination of play or looseness in the shifter mechanism
  • Prevention of transmission wear or mis-shifts
  • Reliable long-term performance
  • Improved driving enjoyment, especially in sports-oriented Porsche models

This part is a cost-effective way to revitalise the precision of the Porsche manual gearbox.

Product Information
Product Information
Ignition HT Lead Cylinder 1.
The ignition lead (high-tension wire) 477905441 is a factory-spec wire that carries high-voltage spark from the distributor or coil to the spark plug(s) on the Porsche 924. It ensures the spark reaches the plug at the correct moment and with sufficient strength for reliable combustion.

Fits:
Porsche 924 1980 - 1985

Diagram ref no 26

What this Ignition HT Lead does:
Delivers a clean, strong spark from the ignition system to the spark plugs, enabling efficient combustion and reliable engine starting.
 Provides high-quality insulation to prevent electrical leakage or arcing, ensuring spark integrity even under heat and vibration typical in the engine bay.
 Maintains consistent resistance and electrical characteristics, resulting in stable ignition timing, smoother running, and reduced misfire risk.
 Replaces worn, cracked, or degraded original leads to restore original ignition performance - especially important on older cars where insulation can deteriorate over time.
