The APR PCV Top Plate is a factory-racecar-inspired-part that takes a multi-step approach to addressing several performance robbing issues, and critical engine safety concerns, with the factory system. This system include a new billet top plate that replaces the factory PCV with an upgraded unit designed to address various failure points. The system uses an internally baffled chamber to separate oil, and includes a stainless steel oil drain back port. We include new mounting pegs to lift larger full length engine covers out of the way to fit larger hoses, and include a one way check valve to prevent pressure from acting directly on the N80 valve. All fittings are -10 AN. This part is not a complete system as it's a replacement part for our existing MS100199 full catch can system.
