K&N High-Flow Engine Air Filter 33-2480 for Mazda 3/6/CX-4/CX-5 (2012–2025) — Washable, Performance Upgrade

The K&N High-Flow Original Lifetime Engine Air Filter 33-2480 is a washable, reusable performance air filter designed to increase airflow and help support improved engine response for compatible Mazda models.

Designed and built by K&N in the USA, this premium replacement air filter swaps directly into the factory air box for a fast upgrade without modifications. Unlike single-use paper filters, K&N uses layered cotton gauze media that is oiled and ready to filter while permitting higher airflow. The result is a durable, serviceable filter that’s backed by K&N’s limited lifetime warranty and intended to reduce disposable-filter waste over your vehicle’s lifetime.

How will this filter affect my Mazda’s performance?

The K&N High-Flow media is engineered to allow more air into the intake while still trapping contaminants. Increased airflow can help throttle response and support horsepower under the same engine conditions, though gains depend on the engine and vehicle setup.

• State-of-the-art cotton gauze media boosts airflow compared with many stock filters
• Designed for improved acceleration feel in everyday driving
• Tested on racetracks to validate durability under demanding conditions

How often do I need to clean this filter and what’s involved?

K&N recommends cleaning the engine air filter roughly every 75,000 miles under normal highway use; heavy dust or off-road conditions may require more frequent service. Cleaning is straightforward with K&N cleaner and oil kits and can be completed at home in a short afternoon.

• Typical service interval: about 75,000 miles under normal driving
• Uses K&N cleaner and re-oil for correct maintenance
• Reusable design eliminates frequent replacements and reduces waste

Will it fit my Mazda model and is installation difficult?

What makes this filter different from disposable paper filters?

Unlike throwaway paper elements, K&N uses multiple layers of oiled cotton gauze and a durable frame to provide long service life. The washable and reusable design saves money over many replacements and reduces landfill waste compared with disposable filters.

• Four layers of treated cotton gauze for a balance of protection and flow
• Rugged construction intended to last the life of the vehicle
• Backed by K&N’s limited lifetime warranty (limitations apply)

Who this is for: Drivers who own compatible Mazda models and want a straightforward, long-lasting intake upgrade that can improve airflow and throttle response without complicated installation. It’s also a good choice for drivers who prefer lower lifetime ownership costs and reduced disposable-waste from frequent filter changes. If you frequently drive dusty roads or seek maximized performance gains, plan for more frequent cleaning and consider pairing this filter with other intake or tuning upgrades appropriate for your vehicle.
