Product Description

Unlock massive airflow gains and unleash the true potential of your AMG with our M157 5.5L Biturbo Cold Air Intake Spacer Kit. Designed specifically for Mercedes-Benz AMG models equipped with the legendary M157 engine, this bolt-on kit increases fresh air delivery by over 30%, instantly improving throttle response and horsepower.

This kit replaces the restrictive OEM airbox inlet design by lifting the air filters higher, eliminating airflow bottlenecks, and allowing the turbos to breathe freely. When paired with high-flow performance filters (not included), gains of 20–25 rear-wheel horsepower on stock vehicles are achievable, with even higher gains on tuned cars.
