To verify if the 674-071 Manifold Catalytic Converter fits your specific vehicle VIN, you must confirm that your engine’s internal hardware matches the OE part number 285102G445. Because manufacturers often change internal components mid-year, a simple year-range check is insufficient to guarantee a match for your specific VIN.
The Manifold Catalytic Converter weighs 13.97 pounds and is designed to replace the exhaust manifold and converter unit on a Hyundai Santa Fe Sport. We selected this specific converter for our comparison because it aligns with the primary OE specifications for this vehicle’s emissions system. Verifying your VIN is critical because a port mismatch or incorrect oxygen sensor orientation can prevent the vehicle from starting or cause immediate error codes. You should also confirm if your region requires specific California or Federal emissions standards, as a physically fitting unit may not meet local legal requirements. For details on software flashes or ECU re-learning requirements for your specific VIN, you must consult the manufacturer’s technical support page.
What to Check Before Buying the Manifold Catalytic Converter
Confirm these technical details before ordering to ensure the hardware aligns with your vehicle’s unique build.
- Verify that your engine code (such as Theta II or Lambda) matches the bolt pattern and heat shield clearance of the 285102G445 specification.
- Check your production date to identify if your vehicle was built before or after a mid-year hardware revision.
- Confirm that the oxygen sensor ports on your current manifold align perfectly with the new unit’s plug types.
- Ensure the package includes all necessary mounting gaskets and heat shields to prevent exhaust leaks or substrate melting.
- Verify that your local jurisdiction does not require a specific regional emissions certification that differs from the standard federal rating.
Comparing the Manifold Catalytic Converter to Other Options
The Manifold Catalytic Converter serves as a heavy-duty exhaust component that replaces the factory manifold and converter in one assembly. If you require a high-flow ceramic substrate for increased performance rather than a direct OE replacement, you may want to look at high-flow alternatives. Owners who prioritize a perfect factory fitment over aftermarket performance gains will find this specific unit more suitable. For those seeking different material compositions or specific weight reductions, other manifold designs may offer different trade-offs in thermal mass and durability.
You should also review the engine requirements for the 674-071 to ensure it matches your vehicle’s specific power output and configuration.
If you have a Hyundai Santa Fe Sport that requires a direct replacement for the 285102G445 part number, you should choose this Manifold Catalytic Converter. For those with unique production dates or regional requirements, confirm your VIN compatibility with the manufacturer before purchasing.
