Direct Replacement Performance Air Filter for Mercedes Benz (2003-2007) M113K V8 Engine Set of 2

Optimize Supercharger Efficiency: High-Flow Intake Upgrade for the M113K V8

Who It’s For: Engineered for Mercedes Benz AMG owners running the legendary M113K supercharged powerplant who are looking to improve the breathing efficiency of their twin-screw blower.

The Symptom: The factory intake system on the M113K is hamstrung by thick, restrictive paper filters designed for silence and long-term service intervals rather than peak volumetric efficiency. In a forced-induction setup like the 5.4L Kompressor, these paper elements create a significant pressure drop before the air even reaches the supercharger. This restriction makes the blower work harder, increasing parasitic drag and raising intake air temperatures, which often leads to the ECU pulling timing and reducing overall power during spirited driving.

The Engineering Fix: This kit replaces the stock paper media with a pair of high-flow, 5-layer cotton gauze filters. By utilizing progressively finer mesh layers, we allow for a much higher CFM (cubic feet per minute) rating while maintaining superior filtration. The filters feature a 100% polyurethane frame and an integrated urethane bump seal, ensuring a precise, leak-free fit within the factory airbox. This eliminates "air bypass" and ensures that every bit of oxygen is funneled through the cooling media and straight into the supercharger inlets.

Why Mechanics Choose This Kit

• Enhanced Induction Efficiency: By reducing the vacuum restriction in front of the M113K supercharger, this kit allows for quicker boost build-up and improved throttle snap across the RPM range.
• Increased Airflow Velocity: The tall, evenly spaced pleats maximize the surface area for filtration, providing a massive increase in dust-holding capacity and consistent airflow even as the filter ages.
• Bulletproof Construction: Built with 100% polyurethane on all four sides to resist the high-heat environment of the AMG engine bay without warping or cracking like cheaper rubber-based alternatives.
