The APR Intake System is modular. It connects to the factory turbo inlet piping, and provides substantial gains. Those looking to complete the system can opt for this optional APR Turbo Inlet pipe to increase flow over the smaller factory turbo inlet piping. Our inlet pipe is a continuous massive pipe that connects to the turbocharger via a port-matching silicon coupler. The PCV system conveniently connects to the intake via a billet aluminum adapter. Lastly, the system uses a flex coupler that allows adequate engine movement and flex.
