Product Description

The K&N 33-3160 High-Flow Engine Air Filter is a performance upgrade designed as a direct, drop-in replacement for the factory air filter in compatible BMW X3 and X4 models from 2020 to 2023. Built with layered oiled cotton gauze media, this high-flow filter helps increase the volume of clean air reaching your engine, which can support better throttle response and performance compared with restrictive paper filters. The panel design drops straight into the existing air box without modification.

This washable and reusable filter is engineered to last for the life of your vehicle with periodic cleaning - typically every ~50,000 miles under normal conditions - reducing the need for frequent replacement. The pre-oiled cotton media helps trap dust, pollen, and other contaminants while allowing engine airflow to remain high. Backed by K&N's No-Hassle Lifetime Limited Warranty, the 33-3160 delivers long-lasting performance and protection for your BMW's engine.
