K&N High-Flow Engine Air Filter for Mazda 3/6/CX-5 (33-2480) — Washable, Reusable, Lifetime Warranty

The K&N High-Flow Original Lifetime Engine Air Filter (33-2480) is a washable, reusable performance air filter engineered to increase airflow and improve throttle response for compatible 2012–2025 Mazda vehicles.

Designed as a drop-in replacement for factory filters, this K&N unit uses multi-layer cotton gauze media and a durable frame to deliver higher airflow with reliable particle protection. It replaces disposable paper elements, cuts ongoing filter costs, and is covered by K&N’s limited lifetime warranty. Installation typically takes just a few minutes and requires no special tools.

How does this filter affect engine performance?

By allowing greater air volume into the intake, the filter can improve throttle response and support modest gains in horsepower and acceleration. Gains vary by engine and vehicle tuning, but the filter is built to maintain a balance between airflow and filtration efficiency.

• Multi-layer cotton gauze increases air passage compared to stock paper filters
• Pre-oiled media optimizes flow out of the box
• Designed and dyno-tested for automotive performance applications

What maintenance is required and how often should I clean it?

This K&N filter is washable and reusable—cleaning is straightforward using K&N cleaning kits or equivalent products. Under normal highway driving conditions it typically only needs service about every 75,000 miles, though dusty driving requires more frequent attention.

• Clean and re-oil following manufacturer instructions for best results
• Inspect during regular vehicle service intervals or after heavy off-road use
• Cleaning frequency depends on local driving and environmental conditions
