Description

Mazda MX-5 NA (90-97) Mishimoto aluminium radiator manual transmission

The Mishimoto radiator MX-5 NA is a full aluminium replacement for the stock radiator of the 1990 to 1997 Mazda MX-5 NA with the 1.6 or 1.8 engine. The stock radiator with plastic tanks is a known weak spot; this Mishimoto version has TIG-welded aluminium end tanks.

The brazed aluminium core has two rows and is 50 mm thick, for more coolant and better heat dissipation. Ideal for the street, the track or an autocross course. The included 1.3 bar cap raises the coolant boiling point and the magnetic drain plug captures metal debris.
