CTS Turbo N55 Air Intake System – For BMW F2x, F3x & F87 (N55 Engine)

Unlock the full potential of your BMW N55 engine with the precision-engineered CTS Turbo N55 Air Intake System, crafted for performance, reliability, and unmatched sound. This intake is designed specifically for F2x, F3x, and F87 BMW models equipped with the N55 engine, ensuring optimal airflow and perfect MAF sensor compatibility.

✅ Why Choose CTS Turbo Over the Rest?

Most aftermarket intakes fail where it matters most — the MAF housing shape. Factory BMW MAF sensors are hexagonally shaped, yet many intakes use circular designs that result in:

• Erratic idling

• Downshifting issues

• Poor fuel economy

• Incorrect airflow readings (MAF errors)

CTS Turbo solved this problem by designing and casting a proprietary hexagon-shaped aluminum MAF housing, ensuring factory-like metering with enhanced performance.

🔧 Features & Benefits:

• Proprietary Hexagon MAF Housing – Prevents fueling and idling issues caused by incompatible circular MAF housings

• 3.5″ Mandrel-Bent Aluminum Intake Pipe – Powder-coated for durability and optimal airflow

• Reusable 3.5″ Inverted Cone Air Filter – High-flow design for maximum breathing

• Integrated Powder-Coated Airbox – Works seamlessly with your OEM air scoop for true cold air delivery

• Aggressive Induction Sound – Hear your turbo breathe with race-inspired sound

• Laser-Etched CTS Turbo Logo – Premium appearance and branding

• 4-Ply Silicone Couplers & Stainless Steel Clamps – Secure, durable, and leak-free connections

• All Necessary Hardware Included – Brackets and fasteners ensure a rattle-free installation

📈 Performance Gains:

• +10–15 WHP (on stock vehicles)

• Noticeably improved throttle response and torque across the RPM band
