CTS Turbo Mercedes-Benz M177 C63/C63S/GLS63/GLC63S AMG Intake System

Built for the M177

No universal filter on a bracket here. It’s made for the M177 4.0L twin-turbo V8, so it drops in clean and fits right. You’re replacing the entire factory airbox and intake tract with reusable high-flow filters and rotomolded tubes that shrug off underhood heat. Stock car, no tune, you’ll see 12 to 20 HP depending on your fuel and elevation, and it pulls harder everywhere, not just at redline.

Features:

• High-flow reusable air filters
• Rotomolded intake system
• Great sound and power increase

Fitment

Fits these M177 4.0L twin-turbo V8 models:

• 2015–2022 Mercedes-AMG C63 & C63S — sedan, coupe, cabriolet (W205)
• 2017–2022 Mercedes-AMG GLC63 & GLC63S — SUV

Why start with a cold air intake

• Full OEM replacement: airbox, tubes and filters, not just a drop-in element
• 12–20 HP with no tune, and more once you tune it
• Reusable high-flow filters; clean them instead of buying new ones
• Rotomolded tubes that take the heat
• A deeper, louder twin-turbo V8

Installation

Straight bolt-on. It swaps in where the factory airbox sits, hand tools only, no cutting and nothing permanent. About as easy as a mod gets on a C63 or GLC63.

FAQ

Will it fit my car? Fits 2015–2022 C63/C63S and 2017–2022 GLC63/GLC63S.

Do I need a tune? Nope. 12–20 HP on a stock car. A tune gets you more, but you don’t need one.

Will it make my car louder? Yes. A lot more twin-turbo V8.

Is a cold air intake hard to install? No. Hand tools, factory airbox spot, no cutting.
