RENNtech Carbon Fiber Airbox for M156 Engines
New, Never Installed — Discontinued Performance Intake System
This genuine RENNtech carbon fiber airbox is designed for Mercedes-AMG vehicles equipped with the M156 V8 engine and remains new, unused, and never installed. The housing is fully finished in carbon fiber and features the RENNtech logo on the upper section. As this intake system has been discontinued, new examples are extremely difficult to source, especially in unused condition.
According to RENNtech’s original performance documentation, this airbox delivers an increase of approximately 10 horsepower and 10 lb-ft of torque over stock. The sale includes BMC high-flow filters, which serve as direct-fit replacements for the original filters and improve airflow efficiency. Also included are MAF sensor retaining clips, installation instructions, original RENNtech paperwork, and a RENNtech pen.
This intake fits a wide range of M156-powered AMG models as approved by RENNtech.
