Let your car take a deep breath with these Big Boost Pipes from Airtec with much larger bore freer-flowing pipes. With fitment designed to match both OE and Airtec Intercooler connections, this is the perfect starting point to a big intercooler upgrade.Larger diameter pipesAirtec branding on pipeworkPipework for both before and after the intercoolerThis comprehensive kit offers an increase in performance and throttle response thanks to a freer-flowing design due to the smooth surfaces of the silicone hosing both on the hot and cold sides.This kit starts with a gentle taper from 40mm at the turbo outlet to increase by 25% to 50mm at the Airtec intercooler inlet. The 60mm Airtec intercooler outlet then tapers down to meet the throttle body at 49.5mm. This results in a 39% increase in internal diameter through the most restrictive sections of the OEM pipework.
