This Samco Sport boot is the best on the market bar-none, no
Chinese copies here. These elbows are hand made in the UK and fully
inspected before leaving the factory. They are contoured inside and
out to provide smooth, laminar airflow to the throttle body,
creating up to 5hp on your M3/ MZ4.
Special design and construction implemented for proper intake
elbow flexibility (when engine moves on its mounts). SamTech
heat and fluid resistant material is more than just "silicone",
it's designed to hold up to years of weather, high heat, and hard
use without slipping off or peeling and it looks great the
entire time you own it.
