Performance Panel Filter Upgrade for BMW 3.0d Models — K&N Part 33-3028

Give your straight-six diesel the airflow it deserves. K&N part number 33-3028 is a premium, serviceable panel element that drops into the factory airbox on a wide range of F-series BMW diesel models. Built with layered, oiled cotton gauze, this direct-fit filter delivers freer breathing compared with disposable paper elements, helping your engine respond more keenly while maintaining outstanding filtration.

We use this filter on our own cars and have installed it for countless customers at MJ Modifications. Feedback has been consistently positive — crisper throttle response, a richer induction note and the long-term benefit of a reusable filter that saves money every service.

Why this reusable panel filter is a smart upgrade

• High-flow cotton media designed to reduce restriction for sharper response and stronger mid-range pull
• OEM-size, direct-fit element for the standard airbox — no cutting or drilling
• Washable and reusable to reduce running costs and waste
• Durable construction with multi-layer oiled gauze for excellent dust capture and engine protection
• Ideal foundation for tuned and stock vehicles alike
• Typical clean intervals up to 50,000 miles under normal road use
• Backed by K&N’s Million Mile Limited Warranty
