K&N 33-3079 Performance Air Filter – BMW Replacement Panel Filter

The K&N 33-3079 Performance Air Filter is a direct replacement upgrade designed to fit seamlessly into your vehicle’s original airbox. It replaces the restrictive factory paper filter with a high-flow performance element — no modifications or additional parts required.

Key Benefits

Increased airflow through the intake system

Noticeable improvement over standard OE filters

Direct plug-and-play installation

Reusable and long-lasting design

Constructed from K&N’s signature pleated cotton gauze and mesh filtration media, this high-flow panel filter is engineered to improve airflow while maintaining outstanding engine protection. The result is sharper throttle response, improved acceleration, and enhanced overall performance — without compromising filtration quality.

By reducing airflow restriction, the 33-3079 can also help improve fuel efficiency under normal driving conditions, potentially lowering long-term running costs.

Supplied pre-oiled and ready to install, this filter is fully reusable. Simply clean and re-oil using a K&N service kit (sold separately) to restore performance. Under normal driving conditions, cleaning is only required approximately every 50,000 miles.

Unlike disposable paper filters, K&N replacement elements are designed for repeated use — reducing waste and offering a more environmentally responsible solution.

Backed by the K&N Million Mile Limited Warranty, every filter is manufactured to the highest standards for durability and long-term performance.
