Product Description

The K&N E-0659 is a high-performance drop-in engine air filter designed for the BMW X5 and X6 models equipped with the 4.4L V8 engine. This upgrade retains factory fitment while delivering improved airflow, which can enhance throttle response and performance, especially under load or in high-demand driving scenarios.

Constructed with multi-layer oiled cotton gauze and reinforced for durability, this filter allows superior breathability compared to standard paper filters while still offering high contaminant trapping. The reusable design means fewer replacements over the life of the vehicle - and less waste.

Installation is straightforward: remove the OEM filter and install the E-0659 in the original housing. No modifications are needed. Ideal for owners of the BMW X5 or X6 V8 who want a reliable performance-upgrade filter that fits precisely. Fitment confirmed through 2018; coverage for 2019-2025 is unconfirmed at time of listing.
