Cleaner cooler oil with the Feuling filtration system, this by-pass microfilter is designed as an additional filter used in conjunction with the stock oil filter The Feuling filtration system drastically reduces contamination and viscosity breakdown in the oil; protecting the engine from cylinder, piston, ring and bearing wear, cylinder bore polishing and extreme oil temperatures, therefore promoting engine performance, longer engine life and extended oil change intervals This filter/cooler system makes a clean custom look, mounting above the voltage regulator between the frame rails in position to take advantage of the air flow from the front tire The kit includes filter/cooler housing and mounting bracket, oil filter mount, braided steel lines and swivel fittings, spin-on oil filter and all necessary hardware
