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.

- 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.

A mass airflow sensor is used to determine the mass of air entering an electronically fuel-injected engine. The air mass information is necessary for the engine control unit (ECU) to calculate and deliver the correct fuel mass to the engine. Air changes its density as it expands and contracts with temperature and pressure. In automotive applications, air density varies with the ambient temperature and altitude, and this is an ideal application for a mass sensor.

A genuine Porsche original equipment (OE) brake master cylinder it serves as the primary hydraulic pressure generator in the braking system of selected Porsche 911 models the 993 generation.
Fits:
Porsche 993 C2 1995 - 1998
Diagram ref no 9
The brake master cylinder is a critical hydraulic component in your vehicle’s braking system. When you press the brake pedal, this device generates hydraulic pressure that is transmitted through the brake lines to the brake calipers or wheel cylinders at each wheel. This hydraulic pressure forces the brake pads or shoes against the rotors or drums, slowing and stopping the vehicle. A properly functioning master cylinder ensures:
• Consistent brake pedal feel and response
• Balanced hydraulic pressure to all wheels
• Safe, predictable braking performance under all conditions
The master cylinder contains internal pistons and seals that pressurise brake fluid when actuated by the pedal. This pressurised fluid is then routed through the brake lines to the brake calipers, activating the braking force at the wheels. Because it directly influences braking behaviour and safety, the master cylinder must maintain proper internal seals and robust construction to prevent leaks and loss of pressure.
Over time, original master cylinders can wear, develop seal leakage, or lose internal resistance, resulting in:
• Soft or spongy brake pedal feel
• Reduced braking effectiveness
• Brake fluid leaks Uneven pressure distribution.
Replacing worn or failing units restores optimum hydraulic pressure and prolongs the life of your brake system - maintaining the braking performance Porsche engineered for your 993.
Replace the master cylinder if you notice:
• Brake pedal that sinks toward the floor
• Spongy or inconsistent braking feel
• Visible brake fluid leakage from the master cylinder body
• Brake performance degradation
• During a full brake system overhaul

Diagram ref no 1
The master cylinder generates and regulates hydraulic pressure when the brake pedal is applied, distributing brake fluid to the front and rear circuits. It ensures consistent brake response, predictable pedal feel, and reliable stopping performance under all driving conditions.
A worn or failing master cylinder can cause loss of hydraulic pressure, poor pedal feel, or brake fluid leakage - all of which compromise safety. Replacing it with a Genuine Porsche OE unit restores factory braking performance, system integrity, and long-term reliability while preserving vehicle originality.
When to replace:
• Brake pedal feels soft, spongy, or inconsistent
• Brake fluid leaks at the master cylinder
• Internal seal wear causing pressure loss
• Uneven or reduced braking performance
• During full brake system refurbishment or restoration
