4” DIAMETER FOR MAXIMUM PERFORMANCE
034Motorsport engineers identified a serious bottleneck in the factory intake system. The factory, 2.8” turbo inlet size, which necks down even smaller throughout the unit, is by far the largest restriction in the intake system after a performance filter system is installed. Many aftermarket companies, including 034Motorsport, have solved this issue by increasing the turbo inlet diameter, thus warranting an intake that supports the added flow gain. The 4” diameter intake kit is designed to support upgraded 4” turbo inlets that can be used on factory, hybrid, and full frame turbochargers. It has been validated that this intake works with the majority of aftermarket inlet options, but has been optimized to work with the upcoming 034Motorsport 4” turbo inlet.
