The aFe Stage 2 cold air intake is engineered to significantly enhance the performance of your BMW. This system delivers a noticeable increase in horsepower and torque, outperforming the factory intake by a remarkable 56%. Let’s delve into the features that make this intake a top choice for performance enthusiasts.
Unleashing Power with Enhanced Airflow
The Afe Stage 2 Intake’s core strength lies in its ability to optimize airflow. A large, 6-inch conical Pro 5R performance air filter with an inverted top maximizes airflow into the engine. This five-layer progressive, oiled cotton gauze filter ensures superior filtration while minimizing restriction, resulting in increased horsepower and torque. Independent testing has shown gains of 12 hp and 16 lbs. x ft. of torque.
Designed for Efficiency and Protection
This intake system isn’t just about power; it’s about comprehensive performance enhancement. The fully sealed, two-piece design effectively isolates the filter from hot engine bay air. This ensures a cooler, denser air charge, further contributing to power gains. A heat-insulating molded plastic tube replaces the restrictive factory intake tract, smoothly directing airflow to the engine for improved volumetric efficiency. The system also includes dual “kidney bean” style auxiliary air inlets, a signature BMW design element that further enhances air volume.
Durable and Easy to Maintain
The aFe Stage 2 intake is built for the long haul. The air filter is constructed from 100% polyurethane, ensuring durability and allowing for multiple cleaning cycles. The system is housed in a heat-shielding molded plastic housing topped with a vacuum-formed ABS black cover. This cover not only seals out hot air but also adds an aggressive yet refined aesthetic to your engine bay. The cover provides easy access to the filter for routine maintenance. Furthermore, the intake mounts directly in the factory location, ensuring a hassle-free installation process.
Compatibility and Emissions
This aFe Stage 2 intake is compatible with BMW models equipped with both active and non-active steering systems. For details regarding emissions compliance and CARB (California Air Resources Board) exemptions, refer to CARB EO D-550-38. The aFe Stage 2 intake provides a substantial performance upgrade for your BMW, delivering increased power, improved efficiency, and a sleek underhood appearance.
