Product Description

The K&N 33-2468 is a high-flow, washable drop-in panel air filter engineered as a direct replacement for the factory air filter in the 2012-2015 Honda Civic (ninth generation, 1.8L L4) and the 2013-2015 Acura ILX (2.0L L4 base model). Both vehicles share the same Honda K-series platform and airbox configuration. Built with multiple layers of precision-oiled cotton gauze between aluminum wire mesh screens, it delivers significantly more airflow than the restrictive OEM paper filter while maintaining up to 99% filtration efficiency - resulting in improved throttle response and measurable horsepower gains.

Installation is a straightforward drop-in - remove the factory filter and place the K&N directly into the existing airbox with no tools or modifications needed. With a service interval of once every 75,000 miles and K&N's 10-Year/Million Mile Warranty, the 33-2468 is the ideal long-term air filter upgrade for ninth-generation Civic and ILX 2.0L owners. Note: for 2016+ Civic use K&N 33-5045; for ILX 2.4L use K&N 33-2473.
