K&N High-Flow Original Lifetime Engine Air Filter — Fits 2021-2024 Mitsubishi, Nissan, Renault

Boost Your Engine’s Breathing with the K&N High-Flow Air Filter

The K&N High-Flow Original Lifetime Engine Air Filter is engineered to move more air through the intake, supporting responsive throttle and smoother acceleration in daily driving. It’s a washable, reusable upgrade designed to last the life of your vehicle, and it’s backed by a trusted warranty. While individual results vary, many drivers notice a noticeable improvement in engine feel and overall performance when the filter is paired with regular maintenance and sensible driving habits.

Key performance attributes include up to 50% more airflow compared with typical disposable filters, paired with a durable, four-layer filtration system. The media uses premium cotton gauze with a specialized tacking agent to form a precise mesh that traps contaminants while maintaining strong airflow. This balance helps the engine breathe freely without compromise.
