A Quick Look at OE Match
OE Match 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 OE Match 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.
- Often chosen when owners want OE-equivalent quality with sensible running costs, especially for routine service and wear items.
- Typical reasons to replace include restoring reliability, addressing age-related wear, or refreshing multiple components during larger repair work.
- Common defects from incorrect application include noise, premature wear, leaks, or fitment quirks if the wrong variant is selected or fitted with old seals/hardware.
- Watch for symptoms such as unusual noises, early wear, or repeat failures after recent work, which can indicate mismatched parts or supporting items left worn.
- Always cross-check OEM part numbers, read model-year notes, and verify compatibility before ordering.
- 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.

This tunnel wiring harness (sometimes called a “tunnel cable harness”) used in Porsche 911 SC models (G-series) built roughly between 1978–1983. This wiring harness runs through the center of the car, connecting the fuse box to the rear lights, engine, and other electrical parts. It supplies power and signals to key systems, so if it’s damaged, lights, instruments, or other functions may stop working correctly.

Quick Facts about tunbel wiring harness (91161200130)
• Location: Runs through the transmission tunnel
• Connections: Links fuse box to rear lights, engine bay & key modules
• Function: Delivers power and signals to lighting, instruments, and electrical systems
• Failure Symptoms: Flickering lights, faulty gauges, or loss of power to components
• Importance: Essential for safe, reliable operation of multiple vehicle systems
Why Replacement Matters — Key Facts & Benefits:
• Electrical Reliability: Old or damaged wiring in the tunnel harness can cause intermittent faults — lights flickering, instruments misreading, or even loss of power to critical components.
• Safety: Faulty rear lights, inadequate ground connections, or exposed wires could lead to dangerous driving conditions or legal issues.
• Prevent Further Damage: Wires rubbing, insulation degrading, or connections corroding may lead to short circuits. Replacing the harness early helps prevent fires, ECU damage or more costly electrical repairs.
• Restoration & Fit: For those restoring or maintaining originality, having a correct, well-routed harness improves resale value and preserves proper factory spec.

This acts as a progressive load-bearing element, cushioning the suspension when the strut nears full compression. It helps prevent harsh bottoming-out, protecting both the strut and chassis from damage during aggressive driving or over bumps. These components maintain ride quality and handling performance, especially under heavy loading or spirited cornering, keeping the suspension linear and controlled.
Common Issues & Considerations Wear or Deterioration: Over time, the rubber can compress, crack, or lose elasticity, diminishing its effectiveness. This can lead to harsher suspension impacts at full compression. Noise or Harsh Feedback: A worn or hardened bump stop can transmit noise or impacts through the cabin, particularly over rough roads or speed bumps. Sport vs. Standard Suspension: These parts are specific to Sport chassis models. Non-sport setups may not have the same bump stops or use different part numbers, so swapping or replacing must be done accordingly.
