Cold Air Intake Spacer Kit for Mercedes Benz E-Class CLS-Class CL-Class S-Class SL-Class G-Class E55 CLS55 CL55 S55 SL55 G55 (2003-2011) 5.5L

High-Flow Cold Air Intake Spacer Kit for 2003-2011 Mercedes-Benz AMG 5.5L Supercharged (W211, C219, C215, W220, R230, W463)

What it Does: The Cold Air Intake Spacer Kit elevates the air filters within the OEM intake assembly on supercharged 5.5L AMG platforms to relieve flow choke points and optimize volume entering the twin air boxes.

The Stock Mercedes-Benz AMG Intake Restriction

The factory dual airbox layout on the supercharged M113K engine tightly recesses the filter elements against the floor of the lower housing. Under heavy load, the Lysholm-type twin-screw supercharger demands massive instantaneous cfm, but the OEM geometry forces air into a turbulent 90-degree boundary layer immediately upon entering the inlet snorkel. This lack of plenum depth creates parasitic vacuum drop across the panel filters, suffocating mass airflow before it reaches the 74mm or upgraded 82mm throttle body, which exacerbates intake air temperatures (IATs) during hard acceleration.

The Engineering Solution

Precision-machined to exact perimeter tolerances, this intake spacer kit acts as a plenum volume extender between the airbox components. By elevating the air filter element away from the restrictive bottom ports, it converts choked, directional airflow into a stabilized velocity stack effect. The increased volume significantly drops pressure loss across the filtration media, ensuring laminar airflow into the Y-pipe collector without requiring modification to factory MAF/MAP calibration or triggering lean engine codes.

Frequently Asked Questions & Fitment Warnings

Does this fit the W211, C219, C215, W220, R230, and W463 AMG models?

Yes, this is a direct fit for 2003-2011 Mercedes-Benz 55 AMG vehicles equipped with the supercharged M113K 5.5L V8; it does not fit naturally aspirated M113 or M156 6.2L AMG engines.

Are air filters included with this spacer kit?

No, this is a spacer-only hardware kit; compatible OEM-replacement or high-flow panel filters must be reused or purchased separately.
