The Turner Motorsport E46 M54 Silicone Intake boot is designed with a smooth contour for improved air flow compared to the OE corrugated rubber, featuring Stepped flanges to maintain smooth ID transition from air box to throttle body. The Turner intake boot also keeps simplicity in mind, with a one piece design, vs. the OE two-piece design. Installation is a breeze! In just a few minutes, you can replace your old worn boot for a sleek new upgrade! Available in Black, or Blue to give your engine bay some color!

Constructed of 5-Ply reinforced silicone for improved durability over the failure prone OE rubber boot. Silicone also offers reduced thermal conductivity as well as improved resistance to ozone and UV degradation for improved performance and durability.
