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 we've found that filters with extremely low micron ratings create an excessive pressure drop across the filter. They can be so restrictive that the filter by-pass valve can open. With the by-pass valve open, unknown to you NO FILTRATION will occur!
To maximize oil filter performance, Moroso race oil filters have a filtration rating of 27 microns. This results in a maximum pressure drop of only 2.5 psi, which results in more flow, less oil bypass, and maximum filtration performance, which is so important in severe racing conditions. Made with roll-formed threads for a precise, tight fit and with an anti-drainback valve to keep oil in the filter after engine shutdown, they are perfect for any race application.
Filter features are as follows:
3.50" tall x 3.00" in diameter
13/16-16 in. thread
Anti-drain back valve
Relief valve open pressure 20 PSI, canister burst pressure is 280 PSI, 140 sq. in. of filter area.
