K&N High-Flow Engine Air Filter 33-2865 — Washable Lifetime Filter for Audi & Volkswagen, Reusable Performance

K&N High-Flow Original Lifetime Engine Air Filter 33-2865 is a washable, reusable performance air filter designed to increase airflow and help improve engine responsiveness for compatible Audi and Volkswagen models.

This high-flow replacement filter is engineered to sit directly in your factory airbox and deliver a measurable increase in air delivery without sacrificing protection. Built from multiple layers of specially treated cotton gauze and assembled with rugged materials, the K&N 33-2865 is intended to be cleaned and reused rather than discarded, reducing long-term maintenance costs and landfill waste. Backed by K&N’s limited lifetime warranty, the filter is developed and tested for durability and performance in demanding conditions.

How will this filter affect my car’s performance?

Installing the K&N 33-2865 can improve airflow compared with many stock paper filters, which may translate to slightly better throttle response and potential gains under load. Gains depend on the vehicle, engine state, and existing intake restrictions.

• Engineered media increases breathable surface area for more airflow.
• Multi-layer cotton gauze traps contaminants while allowing higher flow.
• Designed for drop-in fit to preserve factory intake geometry.

What maintenance does this washable filter require?

The 33-2865 is pre-oiled and ready to use out of the box; it only needs periodic cleaning rather than full replacement. Under typical highway driving, cleaning is recommended roughly every 75,000 miles, but conditions like dustier roads may require earlier service.

• Pre-oiled—no additional treatment required before installation.
• Clean and re-oil with K&N service kit when visibly dirty or per mileage guideline.
• Reusable design can replace many disposable filters over the car’s life.

Will this filter fit my Audi or Volkswagen?

• Fits select Audi A3, Q3, TT, TTS and multiple Volkswagen Beetle, Golf, GTI, Jetta, Caddy, CC, Eos models.
