$55.19
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2002-2009 Audi A4, A4 Quattro, S4, and RS4 models. See the fitment list below for specific submodel compatibility.
The K&N 33-2209 High-Flow Air Filter is a performance-oriented, drop-in replacement for your vehicle's factory intake system. Engineered with multi-layered, oiled cotton gauze media, this filter improves airflow capacity while providing excellent filtration to protect your engine from contaminants. Unlike standard disposable paper filters that require frequent replacement, this washable media is designed for the entire lifespan of your vehicle.
Installation is straightforward, as the filter is precision-engineered to drop directly into the OE air box without modifications. With a long service interval, this filter only requires cleaning every 75,000 miles under normal highway driving conditions.
- Direct Fit: Installs easily into factory air box.
- High-Flow Media: Layered, oiled cotton designed to increase airflow.
- Washable & Reusable: Sustainable design reduces waste and cost over time.
- Service Interval: Cleaning required approximately every 5 years or 75,000 miles.
- Warranty: Backed by K&N’s 10-Year/Million Mile Limited Warranty.
- Manufacturer Part Number: 33-2209
