BMW E46 Intake Boots & Hoses

BMW E46 Intake Boots & Hoses 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).

Samco Silicone Intake Boot - Red - E46 M3 If you've already replaced the factory airbox of your E46 M3 for a cold air intake kit, the stock rubber intake elbow (which connects the mass air sensor / HFM to the intake manifold) is now your enemy. The stock S54 part has accordian-like grooves on both the inlet and outlet side, which slows down air flow. It's no wonder you don't see this type of restrictive setup on the E46 M3 CSL! 

The Samco silicone intake boot for E46 M3 has a perfectly smooth interior surface, engineered for the best flow and smoothest transision -- no sharp edges or angles to hang up or slow down the air. Made in the UK using a 4 layer silicone design. Unlike the stock E46 M3 rubber boot, which is prone to drying, cracking and leaking, the Samco boot is virtually indestructable and ready for the rigors of heat temperature and extreme conditions. 

This Samco silicone intake boot fits the following BMWs:
2001-2006  E46 M3  coupe & convertible
