K&N Engineering 33-2343 High-Flow Drop-In Air Filter for 2006+ Honda Civic Si

The K&N Engineering 33-2343 High-Flow Air Filter is a washable, reusable replacement filter designed for select Honda Civic and Honda Element applications. Its layered, oiled cotton filter media is engineered to improve airflow while capturing contaminants, helping support increased horsepower and exceptional engine protection.

Designed as a drop-in replacement, this performance air filter installs into the factory air box. The reusable construction is engineered to last for the lifespan of the vehicle when properly maintained, offering a practical alternative to disposable replacement filters. K&N recommends the associated 99-5000 Filter Care Service Kit Aerosol for filter maintenance.

K&N backs this air filter with a 10-Year/Million Mile Limited Warranty and states that the product is proudly made in the USA. The filter is intended for the listed 2006-2008 Honda Civic and 2007-2008 Honda Element applications. Review vehicle fitment before ordering to confirm compatibility with your specific vehicle.
