Argo Manufacturing Engine Oil Filter

Argo Manufacturing Engine Oil Filters: Racing-Grade Protection Built in the USA

When it comes to oil filtration for high-performance and racing applications, Argo Manufacturing occupies a unique space. Founded in 1985, the company designs and manufactures all of its parts and tools for NASCAR and racing circuits entirely in-house in the USA — a distinction that matters when you need precision parts that hold up under race-day stress. While the brand is well known across a broad range of engine oil filter and pit equipment categories, its oil filtration hardware is among its most specialized and respected offerings.

Remote Oil Filter Mounts: The Heart of Argo's Oil Filtration Lineup

Argo Manufacturing's signature contribution to engine oil filtration is its HPF-series remote oil filter mount system. These units are CNC-machined from billet aluminum for optimum oil flow, with porting on both sides for easy installation and efficient oil line routing. The design was specifically engineered to accommodate the increased oil flow demands of today's performance engines — a consideration that separates racing-grade hardware from off-the-shelf solutions.

The HPF lineup offers both single-stage and two-stage configurations. The single-stage mount (such as the HPF301) features a 1-1/2–12 in. thread pattern, 12 AN male inlet and outlet connections, and a bolt-on design for straightforward installation. The two-stage mount adds a 40-mesh, 381-micron stainless screen filter along with a 100 PSI bypass valve, allowing the system to continue filtering oil even under overpressure conditions — a critical safety feature in endurance and oval racing. The filter screen is reusable and designed for quick visual inspection of contaminants and debris between sessions.

• CNC-machined billet aluminum construction for durability and optimized flow
• Single-stage and two-stage mount options to suit different filtration needs
• 381-micron (40-mesh) stainless screen filter on two-stage units for pre-filtration
• 100 PSI bypass valve ensures continued filtration during overpressure events
• 12 AN inlet/outlet connections with bolt-on installation for easy fitment
• Horizontal or vertical port orientation available on single-stage units to eliminate 90° fittings
• Reusable, cleanable filter screen for cost-effective maintenance
