Product Description

The K&N 33-2142 is a washable, reusable panel air filter built as a direct drop-in replacement for BMW's E38 and E39 chassis, covering the 540i, 535i, 740i, 740iL, and the high-performance E39 M5. Constructed from layered, oiled cotton gauze, it's engineered to deliver up to 50% more airflow than a disposable paper filter while maintaining strong filtration.

As a reusable filter, the 33-2142 is designed to last the life of the vehicle rather than requiring periodic replacement, needing only occasional cleaning under normal driving conditions. K&N estimates it can save owners around $250 over 10 years compared to repeated disposable filter purchases, and it's backed by a 10-Year/Million Mile Limited Warranty.

This filter is a strong fit for E39 M5 owners looking to maximize airflow to the S62 V8, as well as 540i, 535i, and E38 7 Series owners seeking a long-term alternative to factory paper filters. Given the span of chassis and engine variants covered, confirm your specific model and year before ordering.
