System 1 Filtration: Race-Proven, Made in the USA

When performance engines demand clean oil and consistent pressure, System 1 Filtration Products delivers. Based in Tulare, California, System 1 has earned a devoted following among professional racers and serious enthusiasts by building filtration components that are simultaneously more durable, more serviceable, and more capable than conventional disposable alternatives. System 1 filtration products are proudly made in the USA, and their reputation stretches from weekend warriors to the top tiers of motorsport.

System 1 oil filters are the cornerstone of the brand. Rather than the paper-element spin-on filters most drivers simply throw away at every oil change, System 1 builds canister-style housings from CNC-machined or cast aluminum fitted with cleanable stainless steel mesh elements. These elements are unaffected by moisture, withstand extremely high pressure, and offer very low resistance to oil flow — critical factors in both race and street engines that live under sustained load. The ability to wash and reuse the filter also makes System 1 an environmentally responsible choice, reducing waste at every service interval.

The lineup goes well beyond the filter housing itself. Replacement engine oil filter elements are available separately so the stainless steel mesh can be refreshed without replacing the entire assembly — a practical advantage for teams running tight service schedules. Engine oil filter covers and engine oil filter caps round out the hardware, giving builders and mechanics every component needed to configure, rebuild, or adapt a System 1 filter installation. The inspection cap design is a particularly clever touch: it lets technicians quickly examine what the element has captured, turning the filter into an early-warning diagnostic tool for internal engine wear.

System 1's oil pumps carry the same performance-first philosophy. The catalog spans high-performance cast iron pumps engineered for Chevrolet small-block and big-block applications, as well as CNC-machined billet aluminum designs covering both wet and dry sump systems — including high-volume models purpose-built for Top Fuel and Funny Car applications. Adjustable pressure settings and anti-aeration technology put precise control of oil delivery in the builder's hands.

It's no surprise that System 1 products are the choice of competitors in NASCAR, NHRA, CART, IRL, Formula 1, Monster Truck, and off-road racing. Whether you're building a dedicated race car or upgrading an everyday street engine, System 1's combination of race-proven engineering, lifetime-use hardware, and USA manufacturing makes it one of the most trusted names in engine oiling.
