- For safety-critical components, confirm specification and fitment carefully and have installation checked by a competent technician.
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 vibration under braking, longer stopping distances, squealing, pulling to one side, warning lights and visible wear to discs and pads.
Brake Pad Wear Sensors — Brake pad wear sensors are replaced when pads are renewed or when warning lights indicate a broken or worn sensor. Symptoms include brake wear warnings even with new pads, damaged sensor cables, or broken clips around the caliper area.
Engine Electrical — Engine electrical parts are changed when there are starting, charging, ignition, or sensor-related faults that affect drivability and reliability, such as intermittent no-start, misfires, rough idle, poor charging, warning lights or heat-soak failures.
Service Parts — Service parts are replaced as routine maintenance to keep the engine and systems reliable, efficient, and protected, often resolving hard starting, rough idle, poor fuel economy and warning lights caused by clogged filters or worn ignition components.
Service Kits — Service kits bundle key service components to simplify maintenance and set the car back to a known baseline, especially useful when catching up on overdue servicing or dealing with general sluggish running, inconsistent idle and reduced performance.
- For brake parts, confirm whether items are OE-equivalent replacements or performance upgrades and check if new fitting kits and sensors are required.
- On service items and kits, match the kit to your exact Porsche model, engine and year, and review what is included so you can add any extra “while you are there” parts.

What This Product Does:
- Regulates engine temperature by circulating coolant efficiently
- Transfers heat from the engine to the radiator for cooling
- Maintains correct pressure and flow within the coolant circuit
- Prevents overheating during heavy load, towing, or hot climates
- Prevents coolant boiling or freezing depending on environment
- Protects engine components from corrosion and scale build-up
Symptoms Of Failing Radiator / Coolant Cooler:
- Engine overheating or fluctuating temperature
- Coolant leaks under the front of the vehicle
- Low coolant level requiring frequent top-ups
- Visible cracks, corrosion, or damaged coolant lines
- Radiator fans running excessively
- Poor cabin heating (on some models)
- Strong coolant smell from the engine bay
- Sludge or discolouration in the coolant tank
- Dashboard coolant warnings or overheating messages
Why Replacement Matters:
- Overheating is one of the fastest ways to cause catastrophic engine failure. Proper cooling system components prevent this.
- Fresh components and healthy coolant protect aluminium radiators, water pumps, thermostat housings, and engine passages.
- Engines run best at optimal temperature. A failing cooling system reduces power and efficiency.
- Replacing a coolant cooler/radiator component is far cheaper than repairing warped heads, blown head gaskets, or damaged cylinder banks.
- Hybrid Cayenne models rely heavily on coolant circulation for both engine and electrical system thermal management.

The water pump circulates coolant from the radiator through the engine block and heads, then back to the radiator to reject heat. This circulation prevents the engine from overheating, preserves optimal combustion temperatures, and protects internal components under load or high temperature conditions. With correct flow rates and seal integrity, the OE Match pump ensures stable thermal management across all driving scenarios.
Over time and mileage, the original water pump can suffer from impeller wear, seal degradation, bearing fatigue or corrosion - especially given the demanding thermal environment of the 996’s flat-six engine. A failing pump can lead to reduced coolant flow, overheating, coolant leaks and potential engine damage. Replacing with a correctly specified OE Match unit restores reliable coolant circulation, prevents overheating, and prolongs engine life.
When to replace:
• Coolant leaks visible at pump housing or around gasket/seal area
• Overheating on idle, in traffic or under load - temperature gauge rising above normal
• Unusual noises from the pump area (bearing hum, whine, vibration)
• After many years or high mileage - as part of preventive maintenance (common recommendation every ~4-5 years / ~60,000 miles)
• As part of a cooling-system overhaul (radiator, hoses, thermostat, belt) to ensure all components are fresh and compatible
• If pump’s impeller shows signs of wear or internal corrosion during inspection

Diagram ref no 18
Over years of use (especially in older air-cooled cars like the 964), the floorboard under the pedals can suffer from corrosion, damage from moisture, wear from foot traffic, or previous repair shortcuts. A compromised floor section can lead to:
• Unstable or flexing pedal base - negatively affecting brake/clutch pedal feel and safety
• Rust penetration into the footwell area - risking structural integrity and reducing resale value
• Poor interior sealing - letting in water, dust, or road grime under the carpets
Replacing the floorboard with a correctly sized OE-Match panel restores structural rigidity, ensures safe pedal operation, and helps preserve the car’s value and integrity.
When to replace. You should consider fitting a new floorboard if:
• The original panel is rusted, corroded, bent or has holes under the footwell.
• You are performing restoration or under-body repairs on a 964.
• The pedal area feels soft, creaky, or unstable under load.
• You observe water ingress or dampness in the interior footwell.
• You are doing a full interior or carpet refresh and want a clean, solid base.

Built to original Porsche specifications, the tensioner uses controlled oil pressure to absorb chain vibration and compensate for thermal expansion, ensuring precise valve timing and smooth engine operation.
Over time, the timing chain tensioner can weaken internally, allowing the chain to develop slack and produce rattling noises, especially on start-up. A failing tensioner can cause timing drift, poor running, and accelerated wear of the guides and sprockets. If left unresolved, the chain may even skip a tooth, risking serious internal engine damage. Replacing the tensioner restores stable chain control, accurate timing, and long-term engine protection.
When to replace:
• You hear chain rattle, especially during cold start
• Fault codes or symptoms indicate timing deviation
• Engine runs rough, lacks power, or shows intermittent misfires
• Visible wear or oil leakage around the tensioner housing
• Chain guides have been replaced during an engine service
• Preventatively during M96/M97 engine rebuilds or high-mileage maintenance

• Use Cases: Head rebuilds; valve-seat re-cut; restoring compressed guide bores; upgrading worn or damaged valve guides; preventive maintenance where valve guide integrity is uncertain.
Oversize valve guides are used when the cylinder-head guide bores have worn or been machined during refurbishment. This set provides a complete, matched group of intake guides, ensuring uniform fitment and valve control across all cylinders. With precision-machined tolerances and excellent heat resistance, these OE-match guides restore the valve train to factory behaviour, eliminating excessive valve play and preventing compression loss, misfires or premature wear.
Perfect for engine rebuilders, restorers, and anyone refreshing a 993 cylinder head, this set supports smooth, accurate valve movement and optimal sealing under the high temperatures and RPM conditions typical of Porsche’s air-cooled performance engines.
Valve guides endure constant thermal cycles, valve-spring force, and high-speed motion. Over time they can wear, enlarge, or become loose - causing:
• Valve wobble and mis-alignment
• Poor sealing at valve seats - resulting in compression loss, misfires, or exhaust leakage
• Increased valve-stem wear, potential seat damage, or premature engine wear
• Reduced engine efficiency, elevated emissions, and unsafe reliability.
Replacing worn or oversized guides with a proper unit restores correct valve operation, extends cylinder-head life, ensures compression integrity, and brings the engine back to spec - critical for performance, reliability, and longevity.

Passenger’s Door Window Switch Left Hand Drive (LHD) – Restore Smooth, Reliable Window Operation
This passenger’s side door window switch is designed for
Porsche 997, 987 Boxster, and 987C Cayman models from 2006
onward (LHD). As the primary control for the electric windows, this switch

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.
