High Flow Air Filter Set, M177 W213 / W222

Excluding GST |
These Weistec filters are compatible with the 4. 0 Liter Biturbo (M177 engine) for the W213 chassis E63S.  When analyzing the factory airbox and flow characteristics we found the placement of the filter in the box to be a significant restriction.  Improvements in filter shape and positioning, combined with our very own high flow element provides a significant flow and power increase across all ranges of the engines power band. 
For maximum results, the combination of our Weistec ECU flash is recommended. 
Key Features:
Adds 5-20 Horsepower
Increased Flow Area
Optimized Airbox fitment over factory filter
Amplifies the performance of your Weistec ECU Tune
