If you're looking to give your luxury sedan a little extra oomph, the Dinan Turbo Inlets are just what you need! These easy-to-install bolt-on upgrades tackle the biggest bottleneck in the factory intake system: the turbocharger inlets themselves. Not only are they cost-effective, but they also serve as a crucial step in your journey to unlock the maximum power hidden within your vehicle.

Let’s face it, the factory plastic inlets are pretty limited. They restrict airflow significantly by dramatically narrowing down to the turbochargers. This restriction can cause the turbochargers to work harder than they should. Thankfully, the talented engineers at Dinan have put in the effort to address this issue through extensive prototyping and testing. Their goal? To ensure you get the most power potential while keeping compatibility with a variety of configurations. The result is the Dinan Turbo Inlets, crafted from glossy UV-coated 2x2 carbon fiber that seamlessly integrates with whatever modifications you have in mind—whether you're sticking with stock airboxes or opting for the full Dinan Cold Air Intake System.

Connecting to the stock turbocharger is a breeze, thanks to an aluminum adapter that uses the same factory locking system. You’ll hear a satisfying "click" when it’s secure, making this one of the quickest and least frustrating installations on the market. The design of the pipe maximizes airflow, boasting an impressive 200% increase in volume compared to stock. This boost in volume is key to achieving those performance gains, which is why the Dinan inlet system has a unique and organic shape.

When paired with the factory airboxes, you can expect average gains of around +11 WHP and +13 WTQ from 2000 RPM all the way to redline. However, the real magic happens when you combine these inlets with the Dinan Cold Air Intake, which delivers cooler air earlier in the intake tract. This combination truly maximizes the efficiency of the entire intake system.

Robust testing on a fully instrumented engine has shown just how beneficial the Dinan Turbo Inlets can be, going beyond what you might see on a dyno or flow bench. Simply put, the F90 M5 and F9x M8 Dinan Turbo Inlets help the turbocharger run at a lower pressure ratio, enhancing its efficiency. This means lower pre-turbine backpressure, reduced turbocharger shaft speeds, cooler compressor discharge temperatures, and the ability to achieve higher boost pressure levels.

• More Power: Max gains of 22 WHP and 18 lb-ft of torque @ 6500 RPM on an otherwise stock vehicle. Average gains of 11 WHP and 13 WTQ from 2000 RPM to redline.
• Outflows the factory inlets.
• Larger internal diameter throughout for maximum cross-sectional area.
• Increased volume—about 200% more than stock (105 cubic inches vs. 35 cubic inches per side).
• Carbon fiber construction for heat insulation and a sleek look.
• Quick and easy bolt-on installation.
