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.

Product Information
Timing chain guide.
Genuine Porsche Original Equipment (OE) timing chain guide used in the timing system. It provides a precisely engineered surface against which the timing chain runs, helping maintain correct chain alignment and reduce chain noise and wear.
Sold each, 2 required per engine. 

Fits:
Porsche 986 Boxster 2.5L / 2.7L / 3.2L 1997 - 2002
Porsche 996 3.4L 1998 - 2001

Diagram ref no 33.

The timing chain guide provides a wear-resistant contact surface that supports the timing chain’s path as it moves over the crankshaft and camshaft sprockets. It helps maintain correct chain alignment, reduces vibration and chatter, and minimises wear on the chain and related components - especially under repeated load cycles and high-RPM conditions.

Installed inside the timing case, this OE guide sits in the chain’s routing path and provides a controlled sliding surface that interacts with the chain links. It works in conjunction with the timing chain tensioner (e.g., 99610517552) to ensure correct chain tension, reduce chain slack, and preserve accurate valve timing as designed by Porsche.

The timing chain guide is a critical wear item in Porsche M96 engines. Over time, the original guide surfaces can wear, crack, or deform due to friction and engine heat. A compromised guide can lead to timing chain noise (often described as “chain rattle”), reduced tension control, or uneven wear of the chain and sprockets.

Replacing worn or failed guides with a Genuine Porsche OE part restores the exact engineered surface, ensures accurate chain control, reduces noise, and helps protect high-cost timing system components - preserving the precision and performance that Porsche designed into the engine.

When to replace:
•  Engine exhibits timing chain noise, especially at start-up or idle
•  Timing chain slack or vibration is observed
•  During major engine service or rebuild
•  When original guide shows cracking, abrasion, or wear scoring
•  Preventive replacement on high-mile engines

Timing chain tensioner blade
Original Porsche Genuine OE timing chain tensioner guide used in the timing system. It provides the guided surface against which the timing chain runs under tension, working together with the timing chain tensioner to ensure correct chain tension and positioning.
Sold each, 2 required per vehicle

Fits:
Porsche 986 Boxster 2.5L / 2.7L / 3.2L  1997 - 2002
Porsche 996 3.4L 1998 - 2002

Diagram ref no 30.

This timing chain tensioner guide is a factory-original Porsche component, engineered to the exact material, dimensions, and performance standards specified by Porsche. Installed within the engine’s timing case, it serves as a precision wear surface for the timing chain under the applying force of the hydraulic tensioner.

The timing chain tensioner guide works with the hydraulic tensioner to maintain consistent tension on the timing chain as it cycles over the crankshaft and camshaft sprockets. It provides a controlled sliding surface that helps prevent slack, reduces chain vibration and noise, and supports accurate cam/crank synchronization throughout the engine’s operating range.

Function: Mounted in the timing chain housing, this OEM guide interfaces directly with the tensioner assembly and the timing chain itself. As the hydraulic tensioner applies pressure, the guide helps distribute that force evenly across the chain’s path, ensuring that the chain remains correctly tensioned and aligned. This contributes to smooth, quiet timing system operation, consistent valve timing, and reduced risk of premature wear on timing chains and sprockets.

Timing chain tensioner guides are critical wear items in Porsche M96 engines. Over time, the guide surface can wear, deform, or develop grooves due to prolonged chain contact and heat cycling. A compromised guide can lead to slack, chain vibration, noise (“chain rattle”), and irregular chain travel - conditions that increase stress on the chain and sprockets, and can lead to premature system wear or failure. Replacing worn tensioner guides with Genuine Porsche OE parts restores the exact engineered surface and interaction with the timing chain and tensioner. This helps maintain quiet, accurate timing operation and protects the engine’s costly timing components.

When to replace:
Noise from the timing chain area (rattle or chatter)
 During timing chain system inspection or overhaul
 Visible wear or plastic debris from the guide surfaces
 High-mileage preventive maintenance
 Whenever the timing system is serviced or the tensioner is replaced

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.
