K&N High-Flow Engine Air Filter for 2012–2015 Acura/Honda ILX & Civic (33-2468) — Washable, Reusable Lifetime

This K&N high-flow lifetime engine air filter (part 33-2468) replaces the factory paper element to increase airflow and help restore throttle response for 2012–2015 Acura ILX and 2012–2015 Honda Civic models.

Engine air filters balance two needs: allowing unrestricted airflow while keeping dirt and debris out of your engine. The K&N 33-2468 uses multi-layer cotton gauze media, durable construction and a washable design so it can be reused rather than replaced frequently. It’s built to fit your factory air box and is backed by K&N’s limited lifetime warranty, offering a long-term filtration option for street-driven and enthusiast vehicles alike.

How will this filter affect everyday driving?

Swapping the stock paper element for a K&N high-flow filter commonly improves airflow and can help the engine breathe more freely under acceleration. You may notice sharper throttle response and steadier performance, especially when merging or climbing hills. The effect varies by vehicle and driving conditions; this part is engineered as a direct-fit replacement to keep maintenance simple.

• Designed to increase airflow compared with standard paper elements
• Pre-oiled and ready for installation out of the box
• Fits directly into the factory air box—no modifications required
• May sharpen acceleration feel depending on vehicle and conditions

What maintenance does a washable lifetime filter need?

K&N filters are reusable and only require cleaning after extended use. Under typical highway driving, the cleaning interval is long—often several years or many tens of thousands of miles—so routine replacement is unnecessary. When the element becomes visibly dirty or performance changes, follow K&N’s cleaning and re-oiling instructions to restore filtration and airflow.

• Clean approximately every 75,000 miles under normal highway conditions
• Use K&N cleaning kit and re-oil per manufacturer directions
• Inspect visually during regular vehicle service intervals
• Reusable—reduces landfill waste compared to disposable filters
