RBS has found this filter to be the cleanest and simplest on the market. The beauty of it is that it fits inside any -4, -6, -8, -10, -12 or -20 thirty seven degree fitting in your fuel system. Screen is very small on the filter to catch the littlest of particles without sacrificing fuel flow. Filter is 250 microns and used by some of the best tuners with the fastest cars in the sport.
Racer can choose size of filter from drop down menu.
