Detailed Description

K&N HP-1004 is engineered as a premium replacement oil filter for engines that require a compact spin-on design with wrench-off serviceability. The pleated synthetic-blend filtration media is built to capture contaminants while maintaining steady oil delivery, which is important for engines that rely on clean lubrication under daily driving and extended service schedules. The filter’s 3.406-inch height and 3.156-inch outside diameter support a direct-fit installation on listed applications.

This part cross-references Wix 51334 and Bosch 15146 for the same application. It is a strong match for drivers searching for a Hyundai Elantra oil filter, Kia Soul oil filter, Subaru WRX oil filter, or Toyota GR86 oil filter replacement. HP-1004 is also listed across many older and newer Asian-market applications, including Hyundai Elantra, Kia Forte, Subaru BRZ, and Toyota 86 fitments.

What This Oil Filter Helps Address

• Engine contamination from suspended debris in motor oil
• Oil drain-back after shutdown that can delay lubrication on restart
• Service difficulty when a filter is installed in a tight location
• Seal wear that can lead to oil seepage at the filter base
• Pressure fluctuations during cold starts or high-flow operating conditions
