K&N Engine Air Filter KNA-2936 — Long-Life 18,000 Mile Replacement, High-Flow Filtration

The K&N KNA-2936 is a long-life engine air filter engineered to deliver up to 18,000 miles of reliable filtration while fitting directly into your vehicle’s factory air box.

Built on K&N’s decades of filtration experience, this replacement air filter uses a premium synthetic or cellulose-blend media (depending on application) to balance airflow and engine protection. It’s designed to meet or exceed OEM specifications, installs quickly in minutes, and offers a longer service interval than many disposable filters—making it a practical upgrade for owners of compatible Citroën, Peugeot, DS, Opel, Vauxhall, and Mini models.

How does the KNA-2936 improve engine protection without restricting airflow?
