The EGR valve is a recirculation control valve that regulates the flow of exhaust gases back into the intake on qualifying Porsche 958 4.2L diesel engines. It’s a critical emissions control and combustion-management component - controlling EGR flow to manage NOx emissions, combustion temperature, and overall engine efficiency. Fits left or right

This EGR valve:
• Recirculates a controlled portion of exhaust gases into the intake to lower combustion temperature and reduce NOx emissions.
• Maintains proper valve flow and sealing to ensure consistent emissions control and engine performance.
• Provides reliable operation, with correct internal valve timing and robust valve sealing to prevent leaks or exhaust escape.
• Restores proper EGR function when the original valve fails, is stuck, or leaks - helping avoid emission faults, poor idling, or performance issues.
A failing EGR valve can cause poor combustion, increased emissions, and reduced engine efficiency, especially on diesel models that rely heavily on proper exhaust recirculation. As carbon builds up or the valve sticks, the engine may experience rough running, hesitation, smoke, or higher operating temperatures. Replacing a worn EGR valve restores correct exhaust-gas flow, maintains emission compliance, prevents exhaust leaks, and helps protect the engine from unnecessary stress or long-term damage.
Consider replacing the EGR valve if:
• There are error codes related to EGR failure or emissions fault.
• Engine shows rough idle, hesitation, or reduced performance under load.
• There’s excessive smoke or poor combustion performance, especially on a diesel engine.
• The original valve is faulty, leaking, stuck, or otherwise degraded due to age / carbon build-up.
• Performing an engine maintenance, overhaul, or emission-system service, especially if the EGR hasn’t been replaced before.

OEMatch EGR - Exhaust gas recirculation — Durability, Sealing, Performance
For Porsche models the exhaust gas recirculation (EGR) system helps control combustion temperatures and reduce NOx emissions by recirculating a portion of exhaust gas into the intake. OEMatch supplies a selection of valves, coolers, sensors and related items to support maintenance and restoration of emission control systems across classic and modern Porsche engines.
Available Types- EGR valves
- EGR coolers
- EGR sensors and solenoids
- Gaskets, pipes and mounting hardware
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original exhaust gas recirculation.
OE (Original Equipment) refers to parts matching original specifications for the exhaust gas recirculation and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM exhaust gas recirculation engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
The EGR system reduces peak combustion temperatures and NOx output while helping to maintain combustion stability. Components operate in a high-heat, contaminant-rich environment and are prone to carbon build-up, corrosion and thermal stress. OEMatch maintains a database of over 4,000 part numbers with more than 8,700 OE cross-references and continues to develop new items to broaden coverage for Porsche applications.
Benefits Include- Restores emissions control and lowers NOx output
- Improves idle stability and throttle response
- Helps prevent damage to turbochargers and downstream sensors
- Carbon deposits restrict valves and passages, reducing flow
- Heat cycling causes cracks or leaks in coolers and pipework
- Electrical sensors, solenoids and seals can fail from corrosion or contamination
Maintaining or replacing worn EGR parts helps a Porsche meet emissions expectations and preserves engine responsiveness. Prompt attention to faulty valves, coolers or sensors reduces fuel consumption, prevents smoke or rough running and avoids secondary failures in turbos or intake systems. Choosing parts matched to original specifications supports consistent function across different model years.
Advantages- Coverage for classic and modern Porsche models
- Parts engineered to match the original form, fit and function
- Replacement seals and hardware provided to simplify installation
Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use calibrated tools and new fasteners where specified.
