Mercedes-Benz B-Class W245 M266 Intake Manifold | 2005–2011 | B180 B200 Air Inlet Manifold Spares

Description

Restore optimum engine breathing, precise air-fuel ratios, and smooth, responsive acceleration to your vehicle with this premium Mercedes-Benz W245 Engine Intake Manifold (Air Inlet Plenum). Specifically sourced and verified for the first-generation B-Class (W245 platform) equipped with the M266 4-cylinder petrol engine (found in B150, B170, B180, and B200 models from 2005 to 2011), this vital induction component is the definitive replacement for a cracked housing, warped mating flanges, or degraded internal runners causing unmetered vacuum leaks.

The Intake Manifold is responsible for evenly distributing clean, filtered intake air into the cylinder head ports for combustion. Because the M266 engine features a highly unique design and sits at a sharp, forward-sloped angle inside Mercedes’ compact sandwich-floor safety chassis, the intake manifold is compactly packaged and subjected to intense engine bay heat cycling. Over time, the specialized composite construction can develop hairline fractures, or the mounting ports can warp. This allows unmetered “false air” to bypass the mass airflow sensor, causing a lean running condition. Typical symptoms include a rough or surging idle, engine hesitation under acceleration, a loss of low-end power, and a persistent Check Engine Light ($CEL$) with fuel trim error codes. Replacing the compromised unit completely restores factory air intake velocity and combustion efficiency.

Manufactured from high-strength, heat-stabilized polymer materials to ensure superior resistance to thermal stress and chemical degradation from oil vapors, this air inlet plenum is built to original factory dimensions. It features precision-molded mounting holes that line up perfectly with the M266 cylinder head and accurate ports to accommodate your original throttle body, vacuum lines, and fuel rail assembly. Trust TP German Auto Spares for fully verified, workshop-tested engine induction, fuel systems, and mechanical spares that keep your Mercedes-Benz driving beautifully on South African roads.

Key Features:
