Turner 4″ Silicone Intake Boot w/MAF Housing – E39 540i M62tu …

Description

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.
