This is the Koyo Aluminum Racing Radiator for the 1.8L, and 2.2 L power plants found in the 93-98 Subaru Impreza with manual transmissions.
Koyo has over 50 years of experience in radiator technology, so it would only make sense if they produced a line of lightweight, high performance radiators. These are usually designed to be used with your factory radiator shroud with little to no modifications.
Made to be a direct drop in for your 93-98 Impreza, just make sure you have your car’s year, make, and model entered in the confirmed applications list. This should be one of the last radiators you will ever have to buy for your car.
