This dry carbon cold air intake kit is custom built for Mercedes M139 2.0T turbo engine for AMG A45 W177 and CLA45 C118. M139 engine sits in a compact engine bay. The turbo reaches extreme temperature during hard driving. Stock plastic intake has poor heat insulation. Heat soak will raise intake temperature, reduce air density and limit turbo response & sustained power output. Our prepreg dry carbon intake is equipped with dedicated front cold air scoop, drawing cool air from front grille and blocking thermal radiation from turbo and cylinder head. Enlarged intake chamber and optimized air path reduce turbulence and intake restriction, boost airflow, improve turbo spool, unleash M139 explosive power and deliver sharp high-pitched turbo induction sound. Direct bolt-on replacement, all OEM MAF sensor and vacuum line mounting points preserved. No cutting required. It works without ECU tuning. Better power and response gain can be achieved with Stage 1 ECU remap, popular upgrade for hot hatch track and mountain road enthusiasts.

1.Prepreg dry carbon one-piece housing, lightweight & high rigidity. Excellent thermal insulation reduces heat soak, stabilizes intake temperature under hard driving and maintains consistent high power output of M139.
2.Optimized enlarged intake runners minimize air turbulence and raise airflow, reduce turbo lag, deliver snappier throttle response, faster low-end spool and stronger acceleration punch.
3.Reusable washable high-flow air filter balances dust filtration and maximum airflow, suitable for daily driving, track days and mountain runs, cuts long-term maintenance expense.
4.Dedicated front cold air duct bypasses hot engine zone, continuously supplies cool ambient air and mitigates power heat loss during prolonged aggressive driving.
5.3D scanned moulding compatible with W177 and C118 chassis, perfectly fits compact engine bay layout. All OEM mounting points for sensors and vacuum hoses reserved, plug & play without modifying stock parts.
6.Premium woven carbon finish upgrades engine bay appearance. Distinctive high-pitched M139 turbo induction scream on acceleration, combines performance improvement with engine bay styling.
