06- Honda Ridgeline 3.5L Air Filter

The K&N Engineering 33-2323 air filter for the 2006–2014 Honda Ridgeline 3.5L is a reusable cotton panel-style air filter designed to improve engine breathing and airflow efficiency. Unlike disposable paper filters, this high-flow air filter element uses K&N's signature red cotton media construction, allowing it to be cleaned and reused indefinitely, making it a cost-effective long-term upgrade for Ridgeline owners seeking better engine performance and filtration.

Measuring 13.25 x 6.875 inches with a 0.875-inch thickness, this filter element fits directly into the factory air intake housing of the 3.5-liter V6 Ridgeline engine. The larger surface area and lower restriction of the cotton media compared to standard OEM paper filters enable improved airflow to the engine while maintaining effective air quality. K&N's pleated cotton design traps contaminants while allowing more volume of clean air to pass through, resulting in measurably improved engine response and subtle power gains under acceleration. This is a genuine K&N part (MPN 33-2323), backed by the brand's quality engineering and available as a single filter element for replacement or upgrade.

Honda Ridgeline owners—especially those who tow, frequently accelerate, or operate in dusty conditions—benefit from the reusable design of this filter. Instead of replacing a disposable filter every 12,000–15,000 miles, owners clean this cotton element with water or K&N's cleaning solution, dry it, apply the provided filter oil, and reinstall it. Over the life of the truck, this dramatically reduces maintenance costs while maintaining or exceeding filtration performance. The filter is an ideal upgrade for stock Ridgeline air intake systems and pairs well with other performance modifications aimed at improving engine efficiency.
