Description
The Mishimoto N52 Silicone Intake Boot (MMHOSE-E90-06IHBK) is a direct-replacement air intake boot engineered specifically for BMW models powered by the N52 engine. Built with steel reinforcement rings molded into the silicone body, it resists collapsing under load so your engine keeps receiving the airflow it needs. Unlike the factory hose, this Mishimoto boot ditches the stock resonator BMW used to quiet the N52, delivering a noticeably sharper intake and engine tone.
As a purpose-built piece of your vehicle’s air intake system, this boot connects into the factory airbox and works with either the single stage or 3-stage intake manifold setups found on N52-equipped BMWs. Understanding what does a cold air intake system do helps explain the value here: the intake tract routes air from the airbox to the throttle body, and a boot that flexes, cracks, or collapses under vacuum can restrict that path. Mishimoto’s silicone construction is built for durability and a long service life, and the included stainless steel worm gear clamps make for a straightforward swap that most installers can complete in under an hour. It’s backed by the Mishimoto Lifetime Warranty for lasting peace of mind.
Vehicle Applications
This intake boot is a specific fit for the BMW 325Ci, 325i, 325xi, 330i, and 330xi, all model year 2006, as well as the BMW 328i from 2007 through 2013. It also fits the BMW 328i xDrive from 2009 through 2013 and the BMW 328xi for the 2007 and 2008 model years. All applications share the N52 engine platform and are compatible with the stock airbox and either single stage or 3-stage intake manifolds.
