Cold Air Intake Kit for 2001-2005 BMW (M3) 3.2L L6: Increased Acceleration and Horsepower

K&N air intake systems are engineered for increased performance, outstanding durability, and sleek aesthetics, and are available in a variety of finishes and powder coatings. The state-of-the-art High-Flow Air Filter helps shield the engine from contaminants, while the meticulously engineered aerodynamic tube design contributes to a guaranteed increase in horsepower and torque. These intakes are designed to improve acceleration, towing, and throttle response while providing world-class protection for the engine.

K&N's intakes are dyno-tested and provide more airflow compared to OEM intake systems. They are easy to install and maintain, with air filter cleaning required only every 100,000 miles. The Replacement Air Filter RU-1032 is designed for the 2001-2005 BMW M3.

K&N cold air intake systems provide a less restrictive path for airflow, increasing the volume of cool, oxygen-rich air into the engine, resulting in an estimated increase of up to 18HP and up to 13 ft.lbs. of Torque. These intake systems allow the engine to breathe and sound as it should, with a growl on acceleration and a return to quiet once at speed.

K&N's air intake horsepower/torque testing is performed on wheel-based dynamometers, and the reports are included with each intake system, ensuring trust in the results. The signature, reusable air filter combines 4 layers of pleated, breathable cotton with K&N's red filter oil to absorb dirt and dust particles, allowing clean air to continue flowing into the engine, and only needing cleaning every 100,000 miles under normal highway driving conditions.

The durable, roto-molded intake tube and custom heat shield help increase the volume of airflow to the engine, while protecting the intake air from the high temperature of the engine bay. K&N's air intake systems are backed by a No-Hassle Lifetime Limited Warranty and will not void the manufacturer's vehicle warranty, providing premium engine protection from a trusted brand.

The entire air intake system can typically be installed in less than 60 minutes with basic hand tools, thanks to the detailed, step-by-step instructions and all necessary parts included. Proudly made in the USA, K&N's air intake systems are trusted for their quality and reliability, and are supported by US-based customer service.
