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:

Solves the problems of loose head studs, The exhaust leak you hear in the 911 may actually be the cylinder head leaking where the studs have pulled loose. As Porsche increased displacement of the 911 engine, the different rates of thermal expansion have caused head studs to break or pull out from the engine case. These latest Dilavar steel head studs have a thermal expansion rate of approximately the same as the alloy case.

Oil tank support rubber buffer
This Porsche Genuine OE Rubber Buffer is an original factory oil tank support mount designed for Porsche 911 (964) models from 1989–1994. This bonded rubber-metal buffer (mounting bush) is used to secure and support the engine oil tank to the vehicle body while isolating vibration.
Sold individually, Typically 2 required per vehicle
Fits:
Porsche 964 1989 - 1994
Diagram Ref No 2 or 3
The rubber buffer acts as a flexible mounting point between the oil tank and chassis, absorbing vibrations and movement generated by the engine and oil system. It ensures the oil tank remains securely positioned while preventing excessive stress on connected oil lines and fittings.
Functions & Technical Role
•  Vibration isolation: Reduces transfer of engine vibrations to the chassis
•  Component support: Secures the oil tank in position
•  Stress reduction: Protects oil lines and connections from movement
•  Noise damping: Minimises vibration-related noise
•  OEM construction: Bonded rubber-metal design for durability and flexibility
Fitment / Position on car
•  Fitting position: Engine / oil system mounting
•  Location: Between engine oil tank and body/chassis mounting points

• System: Engine lubrication / oil tank support
Cross Reference / Superseded Numbers
•   99970332400 - replaced by 9997033240A
Over time, rubber mounts can harden, crack, or collapse, leading to:
•  Increased vibration and noise
•  Stress on oil tank and pipe connections
•  Potential oil leaks or fatigue damage
•  Reduced overall system stability
Replacing worn buffers with genuine Porsche OE parts restores proper mounting support and protects the oil system.
