Intercooler for Mercedes Benz E-Class E43 AMG E400 (2017-2018) 3.0L

Direct-Fit All-Aluminum Intercooler for 2017-2018 Mercedes Benz E-Class (W213)

What it Does: The all-aluminum charge-air intercooler directly replaces the factory heat exchanger on 2017-2018 Mercedes Benz E-Class models to suppress intake air temperatures and prevent thermal throttling under sustained boost.

The Stock Mercedes Benz E-Class Heat Soak and Seal Degradation

The factory charge-air cooling system on the M276 twin-turbo platform relies on composite plastic end tanks crimped to an aluminum core. Under repeated thermal cycling and elevated manifold pressures, these crimped seams become prone to micro-fractures, coolant weepage, and boost loss. Furthermore, the OEM core density is engineered around baseline commuting conditions, leading to rapid heat soak and ignition timing retardation during spirited driving or hot ambient conditions.

The Engineering Solution

This high-efficiency replacement features a 1-row crossflow tube-and-fin core constructed entirely from aerospace-grade aluminum. TIG-welded aluminum end tanks eliminate OEM crimp-seal failure points entirely, supporting higher pressure thresholds without expanding or cracking. Optimized internal fluid passages reduce thermal resistance within the liquid-to-air cooling loop, delivering stable charge-air temperatures and sustained volumetric efficiency under load. It drops into factory mounting tabs for straightforward mechanical integration without modifying factory coolant plumbing.

Frequently Asked Questions & Fitment Warnings

Does this fit the W213 E-Class?

Yes, this is a direct fit for the 2017-2018 Mercedes Benz E-Class equipped with the M276 3.0L twin-turbocharged engine. This unit is strictly for charge-air water cooling; it does not replace the primary engine radiator and does not fit 2.0L inline-4 or 4.0L V8 models, nor does it include integral engine or transmission oil coolers.

Do I need to vacuum bleed the intercooler circuit after installation?

Yes, properly vacuum bleeding the low-temperature secondary cooling circuit is required to prevent air pockets from compromising charge-air cooling efficiency.

The Mercedes Benz Precision Standard

Engineered to meet rigorous European performance requirements, this all-aluminum charge-air cooler maintains strict factory diagnostic parameters without triggering manifold pressure deviations or check engine lights.
