Cold Air Intake M157/M278

M157 Cold Air Intake System

The factory M157 intake system allows hot engine bay air to enter the turbos and forces airflow through a long, restrictive path. This limits performance, increases intake temperatures, and reduces consistency on tuned vehicles.

The DTK M157 Cold Air Intake System is engineered to supply the turbochargers with only cold ambient air, using a fully enclosed, sealed airbox design and oversized high-flow filters.

Unlike typical “open” intakes, this system isolates the filters from engine bay heat and seals against the hood, ensuring that hot air from the radiator and engine compartment cannot contaminate the intake charge.

Key Features & Benefits

• Fully sealed airboxes to prevent heat soak

• Cooler, denser intake air for increased power

• Improved throttle response and turbo efficiency

• Reduced intake temperatures under load

• Consistent performance during repeated pulls

Lower intake temperatures allow for more stable ignition timing, improved reliability, and stronger, more repeatable power output.

High-Flow Filters

The system utilizes oversized, high-efficiency performance air filters with significantly increased surface area, allowing higher airflow while maintaining excellent filtration.

The result is improved airflow to the turbochargers without compromising engine protection.

⸻

Performance

Real-world testing has shown measurable performance improvements, including faster acceleration and improved consistency during high-speed pulls. This intake is especially effective on ECU-tuned and higher-boost M157 setups.
