All turbocharged engines benefit from a proper catch can system and properly venting the crank case pressure is a critcal component in high performance turbo applications – especially big turbo builds. The problem is elevated crankcase pressure will reduce energy transfer across the pistons’ ringpack and causes oil burning/consumption issues. As boost pressure and power levels increase, blowby and crankcase pressure also go up. The stock EcoBoost 2.0L and 2.3L engines use a plastic plate with single 3/8″ vent for evacuating crankcase pressure. Our baffled PCV Plate uses the OEM hardware and gasket and adds (2) shrouded -10AN O-ring ports for proper high performance catch can installations. NOTE: Fits EcoBoost 2.3L Mustang / Focus RS, 2.0L Focus ST / Fusion / Escape and 2.3L Mazdaspeed MZR engines.
