J&L Oil Separator are designed for many of the popular Ford, Mopar and GM vehicles. Why run an oil catch can? During the process of venting crankcase pressure back through your intake track, large amounts of oil in the form of vapors can coat your blower rotors, intake valves, intercooler fins and even dilute your gas lowering its octane level. This happens on all engines and is even worse when supercharged as crankcase pressures are increased. To combat this, we have developed an oil separator of our own design that filters / separates the oil in the vapor and deposits it into the catch can instead of circulating through your engines intake system.
