Forge Motorsport stand for clever, innovative and well engineered products and their Twintercooler is no exception.An intercooler cools the air back down after compressing it through a turbocharger or supercharger which heats it up. Cool air contains more oxygen than hot air so the engine runs better and makes more power. Nowadays almost all forced induction cars come with an intercooler but as with a lot of factory kit the original item isn't necessarily built with tuning an engine in mind and can limit the power you make.Forge's Twintercoolers act as a compact secondary intercooler running alongside the original. This set-up adds cooling capacity but without any additional lag. It's also cheaper and easier than replacing the entire intercooler with a bigger set-up.Forge's clever core design and careful routing ensure maximum cooling with minimum lag.For standard and lightly tuned engines this is a very clever way of doing it.Forge have seen up to 10BHP extra on a test car although ob
