Fitment and Application Details
Fits 2002-2004 Volvo S80, N/A. This Dorman 674-834 is engineered to match the original equipment configuration on the Volvo S80 with cylinders 4, 5, and 6, making it a direct-fit manifold converter for the listed years. This part cross-references Bosch 16443 for the same application.
What This Part Helps Address
- Cracked or leaking exhaust manifold assembly
- Restricted exhaust flow from a failing converter
- Exhaust leaks at the manifold-to-head or outlet connection
- Check engine light concerns related to converter efficiency or exhaust sealing
- Noise caused by a damaged integrated manifold assembly
Installation Notes
