JASS Performance radiator cover suitable for MX-5 NA. This radiator cover not only improves the look of the enginebay, but also directs the airstream directly onto the radiator and covers the opening upwards, where the air usually flows through. This results in cooler engine temperature. The radiator cover is curved at the back to achieve a denser air insulation and stiffness of the cover. The assembly is carried out at the original fastening points using the supplied fastening material.
