After many years of designing and testing racing oil systems and related components, Moroso has determined what's most important to oil filtration. Many oil filter manufactures stress the importance of filtering the smallest particles out of your engine's oil, with reference to "micron ratings" of 10 or less for a filter's efficiency.
With the help of research performed by filtration technology experts, Moroso engineers have determined that particles smaller than 20 microns in diameter are not large enough to produce engine wear. Furthermore, Moroso has found that filters with extremely low micron ratings can create an excessive pressure drop across the filter. They can be so restrictive that the filter by-pass valve can open. With the by-bass valve open, unknown to you - NO FILTRATION will occur!
To maximize filter performance, Moroso Racing Oil Filters have a rating of 27 microns, which produces a maximum initial restriction of only 2.5 psi when tested to SAE j806! The result is less pressure drop, more flow, less oil by-pass and maximum filtration performance important in severe racing conditions.Features:
WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
WARNING: The wires of these products contain chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Wash hands after handling.
