Mustang JLT Oil Separator (2005-2010) Installation Instructions
2005-2010 Mustang JLT Oil Separator
This Oil Separator from JLT will fit 2005-2010 GT Mustangs.
Keep the oil out of your intake with an Oil Separator from JLT for your 2005-2010 Mustang GT. 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, intercooler fins and even dilute your gas, lowering its octane level. This element collects the last bit of oil droplets and drains back into the tank when the engine is shut down. JLT has also included a factory PCV hose for an easy plug and play installation.
