Biturbo Cold Air Induction Kit – Mercedes-Benz C63 / C63S / GLC63 (M177) Twin Turbo/Bi-Turbo Engine

Your M177 Bi-Turbo V8 is starving for air. It’s time to let it breathe.

The 4.0L V8 in your AMG is a masterpiece of German engineering, but it suffers from a restrictive factory design. The stock air filters sit too low in the inlet, choking off airflow and limiting the potential of your turbos.

The UPD Cold Air Induction Kit (CAIK) is the ultimate "sleeper" modification. By utilizing a clever spacer system and high-flow filtration, this kit unlocks massive power gains without requiring you to replace your entire intake piping or ruin the clean, OEM aesthetic of your engine bay. It’s simple, effective, and dyno-proven.

Why Choose the UPD Induction Kit?

1. Massive Airflow Improvement (+30%)

The factory setup only utilizes about 55% of the air filter's surface area because the filters are shrouded by the inlet design. Our kit includes custom spacers that raise the filters up, unblocking the restriction. This simple change opens the filter to 100% airflow and improves the volume under the filter by 50%. More air means your turbos spool faster and work more efficiently.

2. Dyno-Proven Horsepower Gains

We don’t just promise power; we prove it. Dyno tests on stock-tuned motors show consistent gains of 23-25 Rear Wheel Horsepower (RWHP).

• Better than just a drop-in: Customers have seen 18 HP gains over standard K&N drop-in filters when switching to the UPD kit.
• Tuning Potential: If your AMG is already tuned, expect even higher gains as the engine utilizes the extra oxygen.

3. OEM Look, Aftermarket Power

Many AMG owners want performance without making their engine bay look like a science experiment. This kit retains your original factory airbox and pipes. The result is a seamless, "factory-plus" appearance that features subtle Blood Red anodized spacers for a touch of custom style that only keen eyes will notice.

What's In The Box?

This is a complete bolt-on solution designed for easy installation using basic hand tools.

• 2x High-Flow Air Filters: Washable and reusable custom filters designed for maximum velocity.
• 2x Billet Aluminum Spacers: Anodized in Blood Red, these lift the filters to the optimal height.
• Mounting Hardware: High-quality stainless steel German-made bolts to secure the engine covers and airbox seamlessley.
• Note: This kit does not include intake tubes or pipes; it utilizes your existing factory airbox assembly for a perfect fit.
