Mishimoto's silicone intake boot for BMW E90/E92 N52 engines is a reinforced 5-layer silicone hose with molded steel rings to resist collapse under load. It removes the stock resonator to increase intake and engine tone, fits the stock airbox and single- or three-stage intake manifolds, installs quickly, and is covered by Mishimoto's Lifetime Warranty for long service life and leak-free performance.
