K&N Premium Oil Filter HP-4005 for Ford Super Duty (2011–2026) — 20,000-Mile Protection, Welded Wrench-Off Nut

K&N Premium Oil Filter HP-4005 is a heavy-duty canister filter engineered to protect Ford Super Duty engines up to 20,000 miles while offering a welded wrench-off nut for fast, reliable removal.

This oil filter is built for work trucks and commercial-duty Ford vehicles, including F250, F350, F450, F550, F600, F650, and F750 model years listed. K&N designed the HP-4005 to maintain strong oil flow rates, trap harmful particulates with pleated synthetic-blend media, and withstand long service intervals. The robust canister and laboratory-tested construction deliver burst strength and capacity suitable for heavy usage, and a one-inch welded hex nut simplifies removal even when filters are stuck or hard to reach.

How does the HP-4005 support long service intervals?

The HP-4005 is built to stand up to extended oil change schedules recommended for many modern diesel and gasoline engines. Its pleated synthetic-blend filtration media provides high contaminant capacity while preserving oil flow, reducing the need for early replacements. Laboratory testing verifies the filter's burst strength and retention to handle prolonged service.

• Rated for up to 20,000-mile intervals under compatible service conditions
• High-capacity pleated media captures particulates without restricting flow
• Durable canister construction resists collapse and leakage over long runs

Will this filter work with my engine oil type?

The HP-4005 is compatible with synthetic, conventional, and blended motor oils, so it can be used across different maintenance preferences and fuel types. Its design maintains consistent flow and filtration efficiency regardless of oil viscosity. Always follow your vehicle manufacturer's oil specification when pairing filter and oil.

• Works with synthetic, conventional, and blended oils
• Maintains consistent oil flow across temperature ranges
• Designed to meet OEM-type requirements for listed Ford models

How does the wrench-off nut improve maintenance?

The HP-4005 features a welded one-inch hex nut on the canister that allows quick, secure removal with standard tools. This simplifies filter changes on trucks with limited access, reduces time spent battling stuck filters, and helps keep maintenance safer and cleaner. The nut is integrated so it won't loosen during service life.

• Welded one-inch hex nut for fast removal with common sockets or wrenches
• Reduces risk of filter damage when removing stuck canisters
• Speeds up routine maintenance on fleet and heavy-duty vehicles
