Cold Air Intake Kit Spacers and Filters For Mercedes Benz AMG M113K V8 E55 S55 CL55 CLS55, G55, SL55 (2003-2007)

Optimizing Volumetric Efficiency: UPD High-Flow Intake Spacers for the Mercedes M113K V8

Who It’s For: Engineered for Mercedes-Benz AMG owners running the legendary M113K supercharged powerplant who want to stop choking their Kompressor and actually let it breathe.

The Symptom: The factory intake design on the M113K is one of the most significant bottlenecks in the 5.5L AMG platform. In its stock configuration, the air filter sits deep within the lower air box housing, which effectively masks off nearly 45% of the filter’s surface area. This creates a high-pressure drop as the supercharger struggles to pull air through a restricted space, leading to sluggish throttle response and heat soak during spirited driving or back-to-back pulls on the highway.

The Engineering Fix: This UPD Cold Air Induction Kit utilizes a clever spacer system to solve a fluid dynamics problem. By physically raising the high-flow filters out of the restrictive lower inlet, we allow for 100% of the filter’s surface area to be utilized for induction. This increases air volume by over 30% and significantly reduces turbulence within the air box. We’ve replaced the restrictive factory baffles with a streamlined path, allowing the supercharger to reach target boost levels faster and with less effort, resulting in a cooler, denser oxygen charge entering the cylinders.

Why Mechanics Choose This Kit

• Documented Power Gains: This kit is proven to deliver between 20 to 25 rear-wheel horsepower on stock M113K builds, with even higher gains on cars running smaller supercharger pulleys and tunes.
• Enhanced Induction Note: By removing the factory restrictions, you’ll finally hear the characteristic supercharger whine and a crisp induction roar when the bypass valve closes and you bury the throttle.
• High-End Hardware: No cheap plastic here. The kit includes blood-red anodized T6061 aluminum brackets and spacers, paired with German-made stainless steel hardware to ensure an OEM-level fit and finish that lasts the life of the vehicle.

Common Questions

Which Mercedes-Benz AMG models does this intake spacer and filter kit fit?
This kit is engineered for the supercharged 5.4L/5.5L M113K V8 platform across the 2003-2006 E55 AMG (W211), 2003-2006 S55 AMG (W220), 2003-2006 CL55 AMG (C215), 2006 US / 2005-2006 international CLS55 AMG (C219), 2005-2011 G55 AMG (W463), and 2003-2008 SL55 AMG (R230).

Will this fit a naturally aspirated 55 AMG like the 2003-2004 G55?
It is built specifically for the supercharged M113K V8 airbox assembly found on Kompressor 55 AMG models.

What is included in the box?
The kit comes complete with high-flow air filters, anodized T6061 aluminum airbox spacers and brackets, and German-made stainless steel hardware.

What kind of horsepower gains can I expect?
By lifting the filters out of the restrictive lower airbox inlet to expose 100% of the filter media and increase air volume by over 30%, this kit delivers 20 to 25 rear-wheel horsepower on stock M113K builds, with higher gains on tuned vehicles with upgraded pulleys.

Does this kit keep the factory engine bay appearance?
Yes, the spacer system bolts directly to your factory airbox and engine covers so you get increased airflow and a sharper supercharger whine while keeping a clean OEM look under the hood.
