Specifically designed to handle the intake demands of a big Garrett turbocharger, the ATP turbo inlet can also be used to increase flow and maximize power on the stock turbo with the available reduction coupler. Silicone couplers available in red, blue or black. Please note that this turbo inlet is designed to be used with the ATP short ram intake and can accommodate a stock turbocharger.
