The Forza 308/ 328 light weight performance aluminum radiators are a direct replacement OEM style down-flow version with a far more efficient core design. These units have been fitted in Ferrari's up to 700 hp with no cooling issues even in hot humid countries such as Malaysia and states like Hawaii, Arizona etc.
Designed for high horsepower hot climate applications, as close to a direct fit as possible, (we took over a dozen 308 OEM radiators and measured the differences thru the years and came up with a solution to fit all 308's 328' and even GT4 Ferrari cars) The inlets and outlets are the exact same angle as the original Ferrari radiators, the sensor locations are in the exact same spot as the factory radiators also.
The 3.93 liter version has a larger core for the intense cooling requirements. This is the one I currently run in my NA ITB 4 liter.
Our radiators are a custom USA made core and fully handcrafted in the USA. We have fitments for Ferrari 308 GT4, 308 GTS, gtb/gtsi GT4 thru 1985 and also a correct fitting Ferrari 328 version. $1199.00 $1399.00 for 4 liter engine version.
