K&N Universal Oval Chrome Filter 1 9/16 in. Flange 3 in. Base 2 inch Top 3 in. Height (4 Per Box)

K&N Engineering is well-known for making high-flow air filters that help engines breathe better. This universal oval air filter, part number RC-2314, is a popular choice for a wide range of applications, from motorcycles like the Honda CB750K and Kawasaki KZ650 series to other equipment where a compact, high-flow filter is needed. It’s designed to fit various intake angles and diameters, making it a versatile option for custom builds or replacements.

This filter features a 1 9/16 inch flange that can be stretched up to 1/16 of an inch, allowing for a secure fit on different intake sizes. The pliable rubber flange also helps absorb engine vibration, ensuring a solid connection. Because it’s washable and reusable, you can clean and re-oil it for continued use, which is a practical benefit over disposable filters. The design aims to improve airflow, which can lead to increased horsepower and better acceleration.

This particular item comes in a box of four filters, making it a good value if you have multiple projects or need spares. Remember to check the specific flange dimensions against your intake to ensure a proper fit. K&N offers a one-year limited warranty on these filters.
