The AWE S-FLO 4" turbo inlet coupler transitions from a 4.5" S-FLO intake connection to a 4" turbo inlet, enabling use with 4" aftermarket turbo inlet pipes and S-FLO Carbon Intake components. It’s engineered specifically to integrate with AWE’s 4.5" S-FLO parts and larger turbo inlet setups. Designed for compatibility within the S-FLO suite, the coupler supports seamless mating between the carbon inlet hardware and 4" aftermarket pipes without requiring adapter improvisation.
