Description

2008-2012 5.7, 6.1, and 6.4L Hemi with Screw-in Oil Cap

Challenger R/T & SRT8

This crank case breather assembly replaces the cap on the oil fill tube located on the driver's side of the intake of the late model Hemi engine. The base of the breather is CNC-machined from billet aluminum for precise fit, and the included silicone O-ring is specially designed to prevent oil seepage at the base of the breather. The filter base is microfinished for surface protection and good looks, and is easily hand-polished to a mirror-like appearance. The removable filter element is a high-quality reusable unit from S & B Filters, and is securely retained in the filter base by a specially-machined retention groove at the top of the filter base.

The purpose of this crank case breather is to vent unwanted accumulation of pressure in the crankcase, and to provide maximum circulation of ambient air in the crankcase to reduce oil temperatures. The installation of this breather will contribute to increased engine oil life and reduce the possibility of failed engine seals resulting from excessive crankcase pressure. This breather will reduce the effectiveness of the vehicle's PCV system, and it is not emissions-legal.

The included check valve will allow the breather to vent any crankcase pressure that accumulates, but it will not allow ambient air to be drawn back into the engine through the breather under high-vacuum conditions. This valve is beneficial for applications that retain a valve cover vent line, or applications with a very sensitive (or aggressively-lean) PCM calibration.

 

Note 1: This crank case breather will fit earlier Mopar applications using the same screw-in style oil fill cap. This unit will not fit 2015 Hellcat and similar models with the twist-in helix-style thread on the oil cap. For twist-in applications, please see the MBR0019 listed elsewhere.

 

Note 2: Due to manufacturing differences we can not guarantee fitment on non-OEM aftermarket intake manifolds. Will not work with Holley Sniper Intakes or Edelbrock Victor II Intakes.
