BMW Intake Boots & Hoses for BMW 4 Series F32 (2014+)

Clear BMW chassis

The intake boot provides a pathway for air from the air flow sensor to the intake manifold. On most BMWs the boot is made of rubber with an accordian shape that allows the engine to shift and vibrate. As with any rubber component the rubber can dry out and crack and that can lead to serious running and drivability issues. A crack in the boot means that air is entering the engine that is not being monitored by the airflow sensor. The engine computer relies on data from the airflow sensor to set the fuel mixture in the engine. Excess unmetered air can result in lean condition faults, rough running, misfires, and other performance issues. For misfire and lean condition faults, check your intake boots first.

As an alternative to the original rubber, we also offer silicone boots that are both stronger and last longer with a 4-layer silicone design. Samco silicone boots can also decrease your BMW's intake turbulence and restriction by replacing the accordian design with a smoothed internal surface. Samco boots are also perfect as part of a kit to eliminate the factory traction control system (sometimes called an ASC delete boot).

Owning a BMW for any length of time, you are most likely aware of BMW's less-than-stellar reputation for developing weak plastic hoses and other parts. A great example of this are the N55 turbo inlet pipes. Over time, constant temperature swings cause these plastic pipes/hoses to become brittle. This often leads to cracks, splits, or even complete failure, allowing your turbos to suck in unfiltered air. To prevent this from happening to you, we are proud to present our very own Turner Motorsport F-Chassis N55 Upper Silicone & Lower Cast Aluminum Turbo Inlet Hoses!

Turbo inlet pipes serve two very distinct, and differing, purposes. On one hand, the optimization of a turbo inlet pipe will encourage better turbo efficiency and responsiveness by allowing the turbo to ingest more air by way of an unobstructed and larger volume flow path. On the other, you have a more visceral benefit that some may argue is equally important than that of efficiency/flow optimization --- increased sound. No matter which of the distinct purposes is favored, Dinan will deliver on both. Regardless of application, a Dinan turbo inlet replaces the weak, and failure-prone, plastic factory inlet with a more robust carbon fiber one. CNC machined fittings are utilized to ensure proper fitment and guarantee installation as a direct replacement to the OEM inlet. Beyond material and fitment however are the improvements to the characteristics of the primary element in the system, the pipe itself. The stock turbo inlet has incorporated additional features (multiple in some cases) that introduce flow restrictions and turbulence while also reducing turbo noises. All of which are unwanted but easily rectified by removing the various resonators and enlarging (and optimizing) the path for a more uniform flow. The result is an inlet that delivers not only more air and allows the turbo to be more efficient (work less) but also provides the oft-desired amplification to the turbo induction soundtrack. Features: Increased turbo efficiency and reliability courtesy of maximum unimpeded and uniform airflow. Eliminates the factory sound resonator for increased turbo vocalization. More Flow: Up to 24% greater than stock. 24% increase in overall volume over OEM inlet. Average of 10.8% larger internal diameter throughout (maximum cross-sectional area allowed). Carbon fiber construction for increased durability and visual appeal. Direct replacement of OEM turbo inlet. Quick and easy bolt-on installation.
