Front Catalytic Converter 2.5L

This front catalytic converter is designed for Nissan Altima models from 2007 to 2013 equipped with a 2.5L engine. It serves as a direct replacement for the original front unit to restore emissions compliance. The part carries reference number 674-933 for identification. It is not intended for vehicles with different engine displacements or rear exhaust positions.

Sustained Emissions Performance

The converter uses a 400-chamber substrate to maintain conversion efficiency during extended driving cycles. The stainless steel body resists thermal fatigue from repeated heat cycles. Integrated gaskets and an O-ring seal the flange connections against leakage under pressure. It is not suited for engines modified beyond factory calibration limits.

Build Quality And Mounting Hardware

The unit weighs 11.2 lbs and measures 13.39 inches in width for fitment within the factory tunnel. Installation uses four M10×45 galvanized studs with matching nuts and gaskets provided. Twelve M6×12 screws and gaskets secure the branch connection alongside a dedicated branch gasket. No welding or fabrication is required for standard replacement.
