C43 Cold Air Intake (W205)

Mercedes C43 / C400 Cold Air Intake — Carbon Fiber Lid
Coming October 2026 (Please note, some of the images shown are of the previous, plastic design)

Enclosed, Heat-Isolated Design
Our C43/C400 cold air intake system uses a true enclosed design, relocating the intake away from the external V-mounted turbochargers to minimize radiant heat soak and protect intake air temperatures. Unlike OEM and competitor intakes for the M276 platform, our ducting eliminates restrictive bends, significantly improving airflow to the turbos.

75% Larger Filter, More Than Double the Flow
The washable panel filter is 75% larger than the stock M276 filter, delivering more than twice the airflow of the factory setup. Combined with CFD-optimized, venturi-induced intake dynamics and maximum panel coverage, the system enhances throttle response and boosts turbo efficiency across the rev range.

Carbon Fiber Lid — Built to Last
The ZAC Motorsport C43/C400 intake now features a carbon fiber lid, replacing the factory-style plastic cover used on earlier intake designs. Carbon fiber holds up to sustained underhood heat without warping, so the lid keeps its fit and finish over the long term — not just on install day.

OEM-Style Fit, Plug-and-Play Install
Designed for a seamless fit and finish worthy of your Mercedes C43 or C400, the system retains all factory sensors for a hassle-free, plug-and-play upgrade — no tuning or sensor relocation required.
