Overview

The SPS Motorsport radiator is a high-flow, black aluminum radiator designed for the Mazda MX-5 NB/NBFL. It features fully welded housings, unlike the original radiator's clamped points which are prone to leaking. With a core size of 63.5x32cm and a thickness of 5cm, this radiator offers very good cooling results for enhanced engine temperature management.

It attaches to the original mounting points for plug-and-play installation, and original fan shrouds can be fitted to the welded threaded pieces. The cooler is also compatible with SPS Motorsport's conversions.
Show original supplier description
The SPS Motorsport radiator is a direct replacement for the Mazda MX-5 NB/NBFL, crafted from aluminum with a discreet black finish to enhance the engine bay's appearance. Its core measures 63.5x32cm with a 5cm thickness, engineered to provide significantly improved cooling performance compared to competing products, ensuring the engine remains within optimal temperature ranges even under demanding conditions. Installation is straightforward as it utilizes original mounting points, allowing for a plug-and-play fit. The original fan shrouds can also be attached directly to the welded threaded pieces on the radiator. This cooler is fully compatible with all SPS Motorsport conversions. **Important Fitment Note:** This radiator **does not fit plug and play for vehicles equipped with air conditioning**. For these applications, the SPS Fan Shroud Kit is required. It is also recommended to check and carefully tighten the lower drain plug before installation.
