Air Induction Kit for Mercedes Benz (2007-2011) AMG C63 E63 CLS63 M156

Optimize the Atmospheric Flow: UPD Cold Air Induction Kit for the M156 V8

Who It’s For: Engineered for Mercedes-Benz AMG owners running the legendary M156 6.2L naturally aspirated powerplant who want to reclaim the power lost to restrictive factory airbox geometry.

The Symptom: The factory intake system on the M156 is designed with a heavy emphasis on cabin luxury and noise suppression rather than raw volumetric efficiency. The OEM airboxes bury the filters in a restrictive plastic tray, creating a bottleneck that forces the engine to struggle for oxygen during high-RPM transitions. This leads to a slightly delayed throttle response and a power delivery that feels choked when you’re pushing toward the redline, especially in heavy chassis like the S63 or ML63.

The Engineering Fix: The UPD Cold Air Induction Kit (CAIK) is a precision-engineered solution that addresses the fluid dynamics of the M156 intake path. By utilizing high-quality aluminum spacers and brackets, we raise the air filters out of the restrictive OEM inlet "well." This modification increases the effective filter surface area from a measly 55% to a full 100%, allowing air to flow under and across the entire element. By smoothing out these turbulence zones, we increase air density and velocity, ensuring the throttle bodies are fed a constant, high-volume charge of oxygen.

Why Mechanics Choose This Kit

• Proven Power Gains: Dyno testing confirms 20 to 25 rear-wheel horsepower gains on stock M156 engines, with even higher margins on vehicles running aftermarket ECU tunes.
• Acoustic Transformation: This kit maintains the clean OEM engine bay aesthetic but removes the "muffle" of the stock boxes, providing a sharp, aggressive induction growl that perfectly complements the M156’s signature exhaust note.
• Premium Hardware: Every kit includes blood-red anodized aluminum components and German-made stainless steel hardware, ensuring the system can withstand the extreme heat cycles of a high-performance V8 engine bay.

Common Questions

Which Mercedes-Benz AMG models and engines does this kit fit?
This kit fits 2007-2011 Mercedes-Benz C63 AMG (2007 international, 2008-2011 US), E63 AMG, and CLS63 AMG models equipped with the naturally aspirated 6.2L M156 V8 engine.

Will this fit an AMG equipped with the 5.5L BiTurbo M157 engine?
This kit is engineered specifically for the naturally aspirated 6.2L M156 V8 airbox geometry. Vehicles with the 5.5L BiTurbo M157 engine use a different intake spacer kit.

What is included in the kit?
Every kit includes blood-red anodized aluminum airbox spacers, mounting brackets, and German-made stainless steel hardware.

How much horsepower does this induction kit add?
Dyno testing shows 20 to 25 rear-wheel horsepower gains on stock M156 engines, with higher gains on vehicles running an aftermarket ECU tune, achieved by lifting the filters out of the restrictive lower airbox tray to expose 100% of the filter surface area.

Does this kit keep the factory engine bay appearance?
Yes, the spacers and brackets integrate directly with your factory airboxes so you retain the clean OEM engine bay look while unlocking a sharper induction growl.
