BMW 135i 335i 35i N55 2010-2013 (E9X E8X) Inlet Hose

do88 Performance turbo inlet designed for drop-in fitment in your BMW 135i 335i 35i N55 2010-2013 (E9X E8X)

Key features

• More oxygen to your engine, less vacuum, and better flow!
• Airflow (59mm version) at 0.175 bar / 2.54 psi pressure drop: 1049 CFM (660 CFM), 59% higher than original! See diagram under product images.
• 3D free-form designed inlet hoses of the highest quality.
• CNC-machined adapters for the turbo inlet.

Considerations

The efficiency of a turbocharged car is directly dependent on the inlet temperature and back pressure in the system. What is sometimes forgotten is that good flow before the turbocharger is equally important for it to operate efficiently. Reduced vacuum and cold intake air allow the turbo to pump a larger air mass, which ultimately affects the amount of oxygen reaching the intake – this generates power. In short, there are significant power gains to be had with a good intake system! Throughout our years of development, we have come to see the clear connection between intake temperature, flow to the turbochargers, and how this affects the car's power.

do88 Turbo Inlet Hose

We began our development by 3D scanning the entire available space in the car to rationally work with the products in a CAD environment. The entire system is flow-optimized; radii and angles have been reworked repeatedly to achieve the best results! The finished product is CFD-verified and, of course, flow-verified in our own Superflow SF-1020 flow bench, so that you, as a customer, know what you are buying. The hoses come in a black finish and are delivered with a CNC-machined adapter that connects to the turbo's inlet.
