Fitment & Compatibility
Use the fitment table below to confirm the correct year and turbocharged Cayenne application. If you are replacing only one sensor, confirm the original part number and bank location before ordering.
Turbocharged Porsche fitment can look straightforward until bank location and harness routing get involved. We have been handling that kind of parts matching for over 20 years, and it still pays to verify the original sensor before ordering.
