Description

Mazda RX-8 (04-08) Mishimoto aluminium radiator manual transmission

The Mishimoto radiator RX-8 is a full aluminium radiator for the 2004 to 2008 Mazda RX-8 with manual transmission. The high-revving 13B-MSP rotary produces a lot of heat, especially on track or with extra power, and that asks more than the stock radiator can deliver.

This radiator is engineered to increase cooling efficiency by up to 30 percent. It has a brazed two-row aluminium core 40 mm thick, TIG-welded polished end tanks and a direct fit with no cutting or welding. Suitable for stock as well as turbocharged or supercharged engines.
