CSF 2863 High-Performance All-Aluminum 2-Row B-Tube Radiator for 1999-2005 Mazda Miata

Fits 1999-2005 Mazda Miata models (10th Anniversary, Base, LS, Mazdaspeed, SE, Shinsen).

Maintain optimal engine temperatures on the street or the track with the CSF 2863 High-Performance All-Aluminum Radiator. Specifically engineered for the NB Mazda Miata, this radiator replaces the restrictive factory unit with a heavy-duty 42mm 2-row core. Unlike standard radiators that use "O-shaped" tubes, CSF utilizes exclusive B-Tube technology. By using a seam-brazed "B" shape, the heat transfer surface area is increased by approximately 15%, providing the efficiency of two smaller tubes within a single 42mm footprint while allowing for a lighter, stronger construction.

This radiator is a true drop-in solution, requiring no modifications for installation. It is designed to accept all factory mounting points, fan shrouds, AC condensers, and "quick-connect" hoses. Every unit is finished with a 1-hour "Mirror Finish" hand polish for a show-ready look that matches its race-grade performance.
