Metco Motorsports MBR0019 Twist-In Style Valve Cover Breather for Dodge Hemi

This breather installs as a direct replacement for the oil fill cap in Gen III Hemi applications that use a twist-in oil cap, and absolutely no modifications are required for installation. The precision-machined helix in the bottom of the billet stand fits tightly into the fill tube, and the seal is maintained by the included o-ring.

In supercharged applications, combustion pressures invariably find their way into the crank case, and this pressure contributes to pumping losses, elevated oil temps, and premature failure of engine seals. The breather serves as a high-flow vent to allow any pressure that builds to easily vent into the atmosphere.

This breather is fitted with our proprietary APV one-way check valve, so while internal pressures can pass through, outside air cannot be drawn through the breather and into the inlet tract of the engine. Your engine tune will not be affected by the installation of this breather.

Like all Metco breathers, this unit is CNC-machined from 6061 aluminum, and micro-finished on the exterior surface. The filter is a high-quality reusable unit manufactured in the USA.

NOTES:

• This adapter will fit all late model Mopar applications using the twist-in style oil fill cap. It will not fit models like the 5.7L, 6.1L, and 6.4L Hemi engines that use the screw-in oil cap.
• NOT LEGAL FOR SALE OR USE IN CALIFORNIA
