Technical Details and Features

The K&N HP-4005 oil filter utilizes high flow premium media designed to trap contaminants effectively while maintaining optimal oil flow. The inclusion of an anti drain back valve prevents oil from draining out of the filter when the engine is off, reducing wear during startup. A bypass valve ensures oil continues to circulate even if the filter becomes clogged, protecting the engine under harsh conditions. The Viton rubber gasket provides a durable and heat-resistant seal, minimizing the risk of leaks. The spin-on design with a 1-inch removal nut simplifies filter changes, especially for Ford F-250 Super Duty and F-350 Super Duty owners. The filter’s thread specification (1-1/16 in. - 16) ensures compatibility with the specified vehicle models.
