High performance aluminum radiator suitable for Mazda MX-5 ND 1.5 and 2.0. The radiator features one of the finest fin and piping technologies in the radiator, resulting in better airflow and better cooling of the engine. The water cooler fits Plug and Play into all MX-5 ND models and offers a direct OEM replacement with enormously improved cooling performance. With its B-Tube technology, the CSF radiator has a much better cooling compared to other radiators. In the B-Tube system, the tubes inside the radiator are not round (O-tube) as in other radiators, but are in the shape of a B's to give the water more surface to cool.
