The Turner Motorsport E39?M62tu 4" 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!?
The intake boot is a regular issue especially for BMW's, nearly all vehicles have a boot manufactured from rubber with an accordion section in the design for flexibility. This flexible section is typically where the failure comes from leading to vacuum leak engine codes, rough idle, and increase fuel consumption.?
When you upgrade to a Turner silicone intake boot you get a perfect fit that will not only outlast the OE design (meaning any vacuum leaks and rough idle), while also smoothing out airflow within the intake tract.
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.?
