The Focus ST & RS Models have been massively popular and tuning of these fast fords have been taken to amazing new levels, unfortunately, the cooling radiator has always been a weak point, this is where are AIRTEC alloy radiator comes into play.

We opted for a huge 40mm core normally found on our Cosworth radiators it was perfect! but due to its size we needed to make the fitting more adjustable. We opted for adjustable billet lower locating pegs, these help position & fitting @ the same time stop twisting of the radiator while trying to fit.
