Description

Mazda MX-5 NA (90-97) Mishimoto X-Line aluminium radiator 3-row

The Mishimoto X-Line radiator MX-5 is the heaviest-duty aluminium radiator Mishimoto builds for the 1990-1997 Mazda MX-5 NA. Instead of two rows, the X-Line has a three-row, 52 mm thick core for maximum cooling capacity on track days, autocross and drift events.

The tubes are 16 percent thinner than stock, giving more surface contact and more contact points for heat transfer. The three-row design creates extra air turbulence and therefore higher cooling efficiency. The radiator is 100 percent brazed aluminium with polished end tanks and is a direct replacement for the stock unit, with no cutting or welding.
