Filter Element 14 x 3-1/16

The K AND N ENGINEERING Filter Element 14 x 3-1/16 (MPN E-3743) is a premium cylindrical air filter designed for high-performance automotive applications where superior airflow and engine protection are essential. This filter element serves as the replacement core for K&N's reusable air filtration systems, providing a cost-effective solution for maintaining peak engine efficiency. It is particularly suited for modified engine builds and performance vehicles.

K&N's proprietary oiled cotton media technology allows this filter element to capture contaminants while permitting maximum volumetric airflow compared to disposable paper alternatives. The nominal dimensions of 14 x 3-1/16 inches provide substantial filtration surface area, reducing restriction across the intake tract and supporting responsive throttle response and fuel efficiency. The high-quality construction with reinforced end caps ensures durability through multiple service cycles, and the oiled media requires only periodic cleaning and re-oiling.

Technicians and tuners favor K&N filter elements for naturally aspirated, turbocharged, and supercharged applications. This filter is ideal for those who prioritize performance and engine longevity, as it effectively traps fine particulates that could otherwise reach cylinder walls. Its reusable design eliminates the waste and recurring expense associated with single-use filters, making it a smart choice for serious automotive enthusiasts.
