It is engineered as an OE-style replacement with high precious metal loading and a rare-earth mixture to help maintain emissions performance and keep the MIL light off under demanding conditions.

Key Features

• Exact-fit catalytic converter for direct replacement use.
• High precious metal loading for stronger emissions control performance.
• OE-style rare-earth formulation for consistent operation.
• Gaskets included for the installation process.
• Fits 2002-2006 Nissan Altima, rear.

Detailed Description

Davico Dealer Alternative Exact-Fit Catalytic Converter 48120 is built for 2002-2006 Nissan Altima rear applications and follows an OE-style fitment approach. The design uses 9 times the precious metal loading of a standard aftermarket converter, along with an OE mixture of rare earth materials, to support emissions system function under severe operating conditions. This makes the 48120 a practical replacement when the original converter is no longer performing as required. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Is Used For

• Replacing a worn or inefficient catalytic converter.
• Addressing emissions-related fault codes tied to converter performance.
• Restoring exhaust flow and aftertreatment function.
• Reducing the chance of an illuminated malfunction indicator light.

Installation Notes and Tips

Fits 2002-2006 Nissan Altima, rear. Verify the exhaust configuration before installation and confirm the vehicle is not subject to California or New York emissions restrictions noted for this application. Use Davico decarbonizing induction kit 1540ea when specified by the manufacturer. Gaskets are included.

Quality Assurance

Davico positions the Dealer Alternative Exact-Fit line as an OE-style replacement solution for demanding service conditions. The 48120 is built to match the application requirements of the original part while using a high-loading catalyst formulation for consistent emissions control.
