BMW Intake Boots & Hoses for BMW 3 Series E46 (1999-2005)

Clear BMW chassis

Please ensure your correct model is selected

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).

If you're seeking to eradicate vacuum leaks and enhance the overall airflow of your intake system, look no further than this comprehensive kit.

The M52TU/M54 air intake boots have gained notoriety for their tendency to crack, resulting in vacuum leaks, triggering check engine lights, and causing various performance issues. The soft rubber boots are constantly exposed to high temperatures from the engine, leading them to become brittle and prone to cracking over time. These cracks permit unmeasured air intake beyond the airflow meter, resulting in rough idling, sputtering, or even engine stalls.

This kit offers a solution by providing both lower and upper air intake boots/hoses for a complete repair. Additionally, as a bonus, the kit includes an ECS Exact-Fit High-Flow Air Filter to optimize your vehicle's intake tract.
