K&N Oil Filter HP-1003 — 20,000-Mile Engine Protection, Welded Wrench-Off Nut, High-Flow

K&N HP-1003 oil filter delivers heavy-duty filtration and a welded wrench-off nut for fast removal while supporting extended service intervals up to 20,000 miles when matched to manufacturer recommendations.

Engine protection starts with clean oil; the K&N HP-1003 is built as a rugged, high-flow canister filter that works with synthetic, conventional, and blended oils. Its pleated synthetic-blend media traps contaminants, the one-inch welded hex nut speeds removal, and the robust housing is lab-tested for capacity and burst strength. This filter is engineered to meet the longer drain intervals many modern vehicles and service schedules require while being backed by K&N’s 1-Year Limited Warranty.

How does the HP-1003 improve oil flow without sacrificing filtration?

The HP-1003 balances high flow rates and retention by using pleated synthetic-blend filtration media that maintains consistent oil throughput under normal and demanding conditions. The internal design reduces restriction so oil circulates quickly while still capturing harmful particles that can accelerate engine wear.

• High-flow pleated synthetic-blend media for steady oil delivery
• Engineered housing to resist collapse under pressure
• Compatible with synthetic, conventional, and blended oils
• Laboratory tested for capacity and burst strength

What makes removal and replacement easier for DIYers and technicians?

K&N added a one-inch welded hex nut to the canister so you can use a standard wrench or socket for fast, reliable removal—no special strap wrench required in most cases. The sturdy construction also resists deformation, which helps when hand-tightening or loosening during service.

• Welded one-inch hex nut for quick wrench-off removal
• Heavy-duty canister prevents tool slippage
• Simplified change-out reduces shop time and effort
• Designed for repeated installations within service life

How durable and reliable is the HP-1003 under extended use?

The filter’s canister and media are designed for burst strength and high contaminant capacity, verified by laboratory testing. While it supports extended service life when paired with appropriate oil and maintenance practices, follow manufacturer service intervals and replace if damaged or excessively dirty.

• Lab-tested for burst strength and contaminant capacity
• Heavy-duty canister resists collapse and corrosion
• Filtration media traps particles that accelerate engine wear
• Protected by K&N 1-Year Limited Warranty
