BiTurbo Cold Air Induction Filter Kit for Mercedes Benz (2011-2017) E63 CL63 S63 G63 S63 SL63 AMG 5.5L M157 Engine

Optimize your M157 BiTurbo Airflow with the UPD Cold Air Induction Kit

Who It’s For: Engineered for Mercedes-Benz AMG owners running the M157 5.5L V8 BiTurbo powerplant who want to extract maximum power without compromising the clean, factory appearance of their engine bay.

The Symptom: The stock Mercedes airbox is a textbook case of packaging compromises over performance. While it looks sleek, the factory air filters sit deep within the housing, effectively masking off nearly 45% of the filter surface area from direct airflow. This creates a significant bottleneck that forces your twin turbos to work harder to pull air through a restricted, turbulent path, leading to sluggish throttle response and a noticeable dip in top-end pull as the heat builds up.

The Engineering Fix: This UPD system doesn’t just replace the filter; it re-engineers the airbox geometry. By utilizing precision-machined aluminum spacers and high-grade German hardware, we lift the high-flow filters out of the restrictive OEM inlet track. This modification increases the available filter surface area to a full 100% and expands the plenum volume under the filter by 50%. The result is an M157 engine that breathes over 30% more efficiently, delivering significantly higher oxygen density to the turbochargers.

Why Mechanics Choose This Kit

• Measurable Power Gains: Real-world dyno testing shows 23-25 rear wheel horsepower gains on stock vehicles, with even higher yields on tuned M157 platforms.
• Improved Induction Acoustics: The increased airflow path provides a more pronounced turbo spool sound and a refined V8 growl under heavy acceleration.
• Premium Hardware: The kit includes blood-red anodized aluminum brackets and spacers paired with stainless steel hardware, ensuring a lifetime of corrosion resistance and a secure fit.
