K&N Engine Air Filter KNA-2480 for Mazda L4 2.0/2.3/2.5L (2010–2025) — Long-Life 18,000 Mile, High-Flow Protection

High-flow K&N engine air filter KNA-2480 is a long-life replacement filter rated for up to 18,000 miles that fits many 2010–2025 Mazda L4 2.0/2.3/2.5L models.

Designed and manufactured by K&N, this Advantage Plus air filter delivers extended service life and robust engine protection while matching or exceeding factory specifications. It replaces the disposable 12,000-mile style with a premium synthetic/cellulose blend media that balances filtration efficiency and airflow for everyday driving and spirited road use. Installation is straightforward — the unit drops into the factory airbox and secures with the vehicle’s original clips and fasteners.

How long will this K&N filter last compared to stock filters?

The K&N KNA-2480 is engineered for up to 18,000 miles of normal highway driving before replacement, which is about 50% longer than many standard 12,000-mile disposable filters. Longevity depends on driving conditions; dusty or off-road use may shorten service intervals. Regular inspection is recommended to confirm service timing.

• Rated service life: up to 18,000 miles under normal highway use
