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).

Flexible silicone smooths the intake tract while allowing for a range of performance intakes fitments. The ultimate in durability!

In most vehicle applications, the rubber intake elbow found in the intake system is not designed for performance or modification. They were designed to get the job done but when you add a performance filter, intake or tune, the stock elbow will start to show it weakness. The stock rubber elbows disrupt air flow as it passes over the accordion sections causing unwanted turbulence and negating the effects of intake modifications.

With high quality 4 ply construction, the Turner intake boot is strong but flexible, ensuring a secure fit on an OEM or aftermarket intake system. A smooth interior ensures unimpeded airflow, while a smooth, unassuming exterior adds to any engine bay.

Benefits:

Improved throttle response,
Increase induction sound
Increased power output - and power output, Best when paired with an ECS drop-in air filter.(ES4461001 or ES4460965)
