Upgrade the intake performance of your BMW N57-powered vehicle with the K&N High-Flow Air Filter 33-3028, designed as a direct replacement for the factory air filter. Engineered using advanced oiled cotton gauze filtration media, this performance panel filter improves airflow into the engine while maintaining excellent filtration efficiency. Designed to fit seamlessly within the OEM airbox, it is one of the most effective and cost-efficient upgrades for BMW 3.0 diesel models.
Increased Airflow & Improved Engine Response
The K&N 33-3028 air filter is designed to reduce intake restriction compared to standard paper filters. By increasing airflow into the engine, it helps support:
-
Improved throttle response
-
Enhanced engine efficiency
-
Potential gains in horsepower and torque
-
Smoother power delivery
This makes it a popular upgrade for both standard and tuned N57 diesel engines.
Advanced Cotton Gauze Filtration Technology
K&N’s signature filtration system uses multiple layers of oiled cotton gauze, creating a high-flow yet highly effective filtration medium. This design allows air to pass through more freely while capturing contaminants that could otherwise damage internal engine components.
Key benefits include:
-
Up to 99% filtration efficiency
-
Multi-layer cotton gauze construction
-
Designed to trap dust, dirt and debris effectively
-
Maintains consistent airflow over time
Washable & Reusable – Lifetime Value
Unlike disposable paper filters, the K&N panel filter is fully washable and reusable. Under normal driving conditions, it typically requires cleaning every 75,000 miles (approx. 5 years).
This provides:
-
Long-term cost savings compared to replacing OEM filters
-
Reduced environmental waste
-
Consistent performance over the lifespan of the vehicle
Each filter is backed by K&N’s No-Hassle Lifetime Limited Warranty.
Direct OEM Replacement Fit
The K&N 33-3028 is designed as a drop-in replacement, fitting directly into your BMW’s factory airbox with no modifications required. It comes pre-oiled and ready to install, making it one of the easiest upgrades for immediate performance benefits.
