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:

Product Information
Spark plug, FR5DTC.
This genuine Porsche OE spark plug is the factory-installed ignition component in air-cooled and early liquid-cooled 911 Carrera and RS engines of the 964 and 993 generations. It provides the correct ignition characteristics for smooth, efficient operation, just as Porsche intended – ideal for service replacements, maintaining consistent performance and the authenticity of classic designs.
Sold individually, 12 spark plugs required per engine.
Fits:
Porsche 964 C2 / C4 1989 - 1993
Porsche 964 RS 3.6L 1991 -1993 M64.03
Porsche 993 C2 / C4 1994 - 1997
Porsche 993 C2S / C4S 1994 - 1997
Porsche 993 RS M64.20 1994 - 1997
Spark plugs are a critical part of the ignition system. Each plug creates an electrical spark inside the combustion chamber that ignites the compressed air-fuel mixture, producing the explosion that powers each engine cylinder. Genuine OE spark plugs ensure this ignition process is consistent, clean, and optimised - which supports smooth idle, strong throttle response, and efficient combustion throughout the rev range.
Functions & Technical Role:
• Ignition ignition source: Generates a reliable, timed spark for each cylinder
•  Optimal combustion support: Maintains a consistent burn for power, efficiency, and emissions
•  OE-matched heat range & gap: Designed to Porsche factory specifications for the 964/993 engine family
•  Durable construction: Quality materials resist normal wear and combustion deposits
•  High RPM performance: Suitable for classic 911 driving conditions
Spark plugs naturally wear from heat, combustion deposits, and electrode erosion. As they age, misfires, rough idle, and poorer fuel economy can develop. Installing Genuine Porsche OE plugs ensures the correct spark gap, heat range, and ignition performance, preserving engine efficiency, responsiveness, and emission stability.
When to replace spark plugs:
•  At Porsche-specified service intervals
•  During routine engine tune-ups or maintenance
•  If experiencing misfires, hesitation, or rough idle
•  When cold starting becomes harder than normal
•  If performance or fuel economy drops
•  While performing engine diagnostics or restoration work
