BMW E46 M3 ECS Silicone Intake Boot Upgrade

The factory-installed intake boot on the E46 M3 uses a ribbed design, connecting the air box and intake manifold at a severe angle. The result is an obstruction and misdirection of airflow, creating turbulence that effectively minimizes intake plenum volume.

The ECS Silicone Intake Boot exhibits a less severe angle and directs air across a perfectly smooth surface.
