K&N RU-4250 Universal Round Tapered Rubber Air Filter (3.75in Flange ID / 5.375in Base / 5in Height)
$94.99
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
The K&N RU-4250 Universal Air Filter is engineered for versatility across a wide range of applications, including racing vehicles, custom automotive intakes, generators, snowmobiles, and tractors. This round tapered filter is built with ultra-strong, molded pliable rubber flanges that absorb engine vibration and ensure a secure, leak-free attachment. The flexible flange material is designed to stretch up to 1/16 of an inch (1.5mm), allowing it to accommodate intake tubes that fall between standard sizes.
As with all K&N universal filters, the RU-4250 features a washable and reusable design, providing a high-flow filtration solution that eliminates the need for frequent disposable filter replacements. This unit is built for durability and performance in demanding environments where precise fitment and reliable filtration are critical.
