K&N Oil Filter: 20,000 Mile Engine Protection with Wrench

The K&N HP-3003 oil filter is a heavy-duty, wrench-off oil filter engineered to protect truck and commercial engines for up to 20,000 miles while making removal fast and simple.

This steel-canister filter combines high flow capacity, pleated synthetic-blend media, and a welded one-inch hex removal nut so fleet technicians and DIYers can deliver reliable oil filtration without fuss. Built to meet or exceed service intervals found in many light-duty trucks, vans, buses, and commercial vehicles, the HP-3003 is lab-tested for burst strength and designed for use with synthetic, conventional, or blended oils.

Which vehicles is the HP-3003 compatible with?

The HP-3003 fits a broad range of heavy-duty and light-duty applications, including many Chevrolet and GMC trucks, vans, bus chassis, select Freightliner and IC Corporation models, and several outboard and industrial engines. Always verify fitment with your vehicle’s year, make, and model or consult the parts lookup before purchase.

• Covers many Chevrolet Silverado/GMC Sierra 2500–6500 variants and classic models (years listed in fitment).
• Compatible with numerous Chevrolet/GMC Express and Savana van models (1996–2016 ranges included).
• Also supports bus and commercial chassis like IC Corporation CE, Thomas Saf-T-Liner, and Freightliner S2G.
• Fits select outboard marine and industrial applications such as Volvo Penta and King Cobra models.

How does this filter support longer service intervals?

High-capacity pleated media and robust construction let the HP-3003 capture contaminants while maintaining steady oil flow, which helps meet extended service schedules when used with appropriate oil and maintenance practices. The internal design balances particle-holding capacity with minimal pressure drop so engines continue receiving consistent lubrication.

• Pleated synthetic-blend filtration media traps a wide range of harmful particles.
• Engineered for high flow rates to maintain oil supply even under load.
• Laboratory-tested for capacity and burst strength to endure extended intervals.
• Compatible with synthetic, conventional, and blended motor oils for flexible service options.

What makes removal and installation easier for shops and DIYers?

The HP-3003 features a welded one-inch hex (wrench-off) nut on the canister for rapid, secure removal using a standard socket or impact tool. The heavy-gauge steel canister and clear sealing surfaces simplify hand-tightening during install and reduce the risk of cross-threading or leaks when replaced correctly.

• Welded one-inch hex nut allows fast removal with common tools.
• Durable canister resists denting and deformation in shop environments.
• Designed sealing surfaces and gasket area for reliable, repeatable installs.
• Works with routine torque practices—follow vehicle manufacturer guidelines.
