W205 C63 & C63 S High-Flow Drop-In Air Filters (M177)

High-flow drop-in air filters for the W205 C63 / C63 S (M177). These OEM-style panel filters improve airflow while keeping the factory airbox for consistent intake temps and stock-like drivability.

Ideal for stock, tuned, Stage 2, and turbo-upgraded builds. Note: the M177 airbox uses two filters — replace both together.
