M157 AMG Aluminum Intake Tubes – W212 W218 E63 CLS63 Upgrade Kit

Let your M157 5.5L AMG V8 breathe properly. These CNC-bent Aluminum Intake Tubes replace the restrictive OEM plastic pipes on W212 E 63 AMG and W218 CLS 63 AMG platforms—improving airflow, throttle response, and turbo efficiency while keeping an OEM+ engine bay appearance.

The factory plastic intake tubes on the M157 5.5L BiTurbo were designed around comfort and noise, not maximum flow. Under heat and boost they can flex and disturb the airflow before the turbos. These aluminum tubes give your E 63 or CLS 63 AMG a more stable, efficient inlet path that supports tuning, harder driving, and repeat pulls.

🔥 Key Features – M157 63 AMG Aluminum Intake Tubes

• High-flow aluminum construction: Rigid tubing that won’t balloon, crack, or deform under boost and heat like aged plastic.
• Smoother turbo inlet airflow: Reduced turbulence and pressure drop before the turbos for more efficient operation.
• Motorsport-grade silicone couplers: Built to handle elevated boost and temperature on tuned M157 AMG setups.
• Direct-fit design: Engineered around factory airboxes and turbo inlets—no cutting, trimming, or guesswork.
• Optional Cerakote thermal finish: Helps control radiant heat in the engine bay and stabilize intake air temps.
• Stealth OEM+ look: Clean routing that fits seamlessly in the W212 E 63 AMG and W218 CLS 63 AMG engine bay.

📈 Real-World Performance Benefits

• Sharper throttle response: Faster, more stable airflow as you roll into boost.
• Stronger mid-range pull: Supports better volumetric efficiency where the M157 shines.
• More consistent performance: Less heat soak and turbulence mean repeatable acceleration, pull after pull.
• Ready for supporting mods: Ideal foundation for ECU tuning, intake spacer kits, downpipes, and turbo upgrades.

✔️ Compatibility – M157 5.5L BiTurbo AMG

Direct fit for the following Mercedes-Benz AMG models equipped with the M157 5.5L V8 Biturbo:

🧰 Installation

• Direct bolt-on replacement for OEM plastic intake tubes.
• Install time: ~45–90 minutes with basic hand tools.
• Works with OEM airboxes and high-flow panel filters.
• No tune required, but pairs best with an ECU calibration and other airflow upgrades.

📦 What’s Included

• Left & right CNC-bent aluminum intake tubes (M157-specific)
• High-temp silicone couplers
• Stainless clamps
• Optional Cerakote thermal coating (if selected)

🔧 Technical Summary: Airflow & Turbo Efficiency

On the M157, the stock intake system includes sharp transitions and pinch points where the plastic tubes meet the airbox and turbo inlets. Under higher airflow this increases pressure drop and makes the turbochargers work harder to reach boost targets.

With smoother-radius aluminum tubing and consistent internal diameter, these intake tubes help reduce those restrictions. The result is more stable boost, improved mass airflow readings, and noticeably crisper throttle response—especially on tuned E 63 and CLS 63 AMG cars.

❓ Frequently Asked Questions

Will these intake tubes fit my M157 AMG?

They fit W212 E 63 AMG and W218 CLS 63 AMG with the M157 5.5L BiTurbo engine. If you’re unsure, send us your VIN and we’ll confirm.

Do I need a tune?

A tune is not required. They work with stock ECU mapping, but tuned cars will see greater benefit.

Are they compatible with performance filters and spacer kits?

Yes. They pair extremely well with high-flow filters and the M157 intake spacer kit to reduce turbulence and improve airflow.

How hard is installation?

Installation is simple with basic tools. No cutting or modifications required; they bolt in following factory routing.
