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

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.
