Oil filter, racing ph8a

After many years of designing and testing racing oil systems and related components, we’vedetermined what’s most important to oil filtration. Many filter manufacturers stress the importanceof filtering the smallest particles out of your engine’s oil, with references to "micron ratings" of 10 orless for a filter’s efficiency.With the help of research performed by filtration technology experts, Moroso engineers havedetermined that particles smaller than 20 microns in diameter are not large enough to produceengine wear. Furthermore, we’ve found that filters with extremely low micron ratings create anexcessive pressure drop across the filter. They can be so restrictive that the filter by-pass valve canopen. With the by-pass valve open, unknown to you—NO FILTRATION will occur!To maximize filter performance, Moroso Racing Oil Filters have a rating of 27 microns, whichproduces a maximum initial restriction of only 2.5 psi when tested to SAE J806! The result is lesspressure drop, more flow, less oil by-pass and maximum filtration performance important in severeracing conditions.
