Show original supplier description
The K&N E-2435 is a high-performance, reusable engine air filter specifically designed as a direct replacement for the 1999-2009 Honda S2000. This filter aims to enhance your vehicle's performance by increasing horsepower and acceleration through improved airflow. Its construction utilizes multiple layers of premium cotton gauze, treated with a proprietary tacking agent, to create a dense filtration media capable of trapping harmful contaminants while allowing maximum air passage. Engineered for longevity and convenience, the K&N E-2435 offers a "lifetime" filtration solution. It requires cleaning only every 75,000 miles under normal highway driving conditions, significantly reducing the frequency of maintenance compared to disposable filters. The filter is pre-oiled and ready for a direct drop-in installation into the factory air box, positioning it as an easy and cost-effective upgrade for S2000 owners seeking performance gains. K&N provides a limited lifetime warranty on this stock replacement air filter, underscoring its durable construction and trusted quality, proudly made in the USA. The K&N E-2435 is built with state-of-the-art construction methods and durable materials, designed to last for the entire lifespan of your vehicle. Its washable and reusable nature also contributes to reducing landfill waste. Key specifications include product dimensions of 13.38"L x 9"W x 7.56"H and a rectangular shape. The filter is considered a replacement part with a vehicle-specific fit type.
