HiFloFiltro HF171CRC-4 Chrome RC High Performance Oil Filter 4-Pack

In this review the HiFloFiltro HF171CRC-4 is evaluated for riders who want a race-capable oil filter that still works for street use; the bottom line is simple: this 4-pack delivers heavy-duty construction and race-grade filtration at a price that beats many premium competitors. The reviewer found it especially appealing for owners replacing Harley filters who need a direct-fit item that installs with a standard wrench and offers the reassurance of the only TUV certified design in its class. If durability and proven filtration matter, this is worth considering.

Key Features

• TUV Certified: Certification ensures consistent manufacturing quality and compatibility across applications for reliable performance.
• Tough steel canister: The heavy duty metal body resists crushing and includes a 17mm cross drilled nut that makes installation and lock wiring straightforward.
• Tri-fiber filtration media: Advanced layering provides higher capacity and improved oil flow while capturing contaminants more effectively than single-fiber designs.
• Rubber coated relief valve: The coated valve seals cleanly under pressure and is compatible with all oil types for dependable operation on track or street.
• Direct OEM replacement: Replaces Harley OEM part 63731-99A for a correct fit without adapter parts or modification.

Who It's For

This product is aimed at motorcycle owners, particularly Harley riders, who want a performance-oriented oil filter that can handle both weekend track use and daily street riding. It suits riders who value proven construction and a filter that installs with common tools, including those who appreciate a chrome finish and a nut at the end for easy removal.

Riders who prioritize the absolute lightest weight or those needing a non-chrome aesthetic for a custom build should consider other options; likewise, those who require model-specific OEM cosmetics rather than a performance replacement may prefer a branded stock-fit alternative.
