Overview

The K&N 33-2406 is a high-performance, drop-in air filter designed as a direct replacement for your factory air filter. It is constructed with cotton gauze and can be serviced, potentially lasting for the lifetime of your vehicle. K&N recommends inspecting and cleaning the filter every 50,000 miles, or more frequently in dusty environments.

This engine air filter is a crucial part of your vehicle's intake system, allowing clean air into the combustion chamber to prevent contaminants from entering the engine. Proper airflow ensures optimal engine performance, fuel efficiency, and reduced emissions. Symptoms of a failing air filter include clogging, moisture contamination, degradation over time, decreased fuel efficiency, and engine misfires.

The K&N 33-2406 is a high-performance, direct-fit engine air filter engineered to replace your vehicle's stock filter. Constructed with durable cotton gauze, this reusable filter is designed for longevity, with K&N recommending cleaning and re-oiling every 50,000 miles under normal driving conditions, or more frequently in dusty environments. As a critical component of the intake system, the engine air filter ensures that only clean air reaches the combustion chamber, preventing dust and debris from causing engine wear. A clogged or contaminated filter can lead to reduced engine performance, decreased fuel efficiency, increased emissions, and even engine misfires. This K&N filter aims to provide superior airflow compared to restrictive factory filters. Key features of this K&N air filter include its ability to not void vehicle warranty, its emissions legality in all 50 US states, and its compatibility with vehicle electronics. It is an environmentally friendly option that directly replaces the factory air filter, offering a performance upgrade. K&N has been a leading manufacturer of washable performance air filters and air intake systems since inventing the reusable high-flow cotton air filter in 1969.
