K&N Oil Filter HP-7042 — 20,000-Mile Protection, High-Flow & Welded Hex

The K&N HP-7042 oil filter delivers heavy-duty filtration and up to 20,000-mile service protection with high flow capacity and a built-in wrench-off hex for fast removal.

The K&N HP-7042 is a purpose-built spin-on oil filter engineered for modern gasoline and diesel engines found in select Jeep Grand Cherokee and Ram 1500 models. It uses pleated synthetic-blend media inside a rugged steel canister to trap contaminants while maintaining steady oil supply. Tested for burst strength and capacity, this filter is intended to match the longer service intervals recommended by many vehicle manufacturers.

How does this filter protect my engine during extended oil-change intervals?

The HP-7042 uses multi-layer synthetic-blend filtration to capture dirt, soot, and other particles that accelerate engine wear. Its media balances filtration efficiency with flow so oil circulates freely even as the element collects contaminants.

• Pleated synthetic-blend media for improved particle capture
• Lab-tested capacity to hold more debris between service
• Designed to support manufacturer-recommended longer intervals

Will this filter work with synthetic and conventional oils?

Yes — the HP-7042 is compatible with synthetic, conventional, and blended motor oils, allowing you to use the lubricant best suited to your driving conditions. The design ensures consistent flow rates so oil pressure and engine lubrication remain stable across oil types.

• Engineered for all common motor oil formulations
• Maintains steady oil flow at operating temperatures
• Suitable for everyday driving and heavier-duty use

What makes installation and removal easier compared with standard filters?

K&N built the HP-7042 with a welded one-inch hex nut on the canister, letting you use a socket for quick, secure removal. The sturdy canister construction resists crushing and simplifies handling during replacement, reducing installation frustration.

• Welded 1" hex nut for fast wrench-off removal
• Heavy-duty steel canister for durability and handling
• Consistent sealing features to prevent leaks after install
