Just ordered one, nice looking unit

Idea is to vent some of the crankcase gases out rather than circulate through the PCV and hopefully reduce chances of carbon buildup on intake valves of DI engine. It’s an old school trick that current environmental policies frown on since the crankcase vapors are vented into the air and not recycled to the intake. It just screws in place of the oil cap and you can always switch back in 2 seconds if worried about dealer and warranty. I think it’s cheap insurance to lessen carbon buildup and who knows how much for professional cleaning of intake valves down the road
 
I think folks are missing all the new technology that is built into the engines and your not going to see the build up unless maybe you drive your car 100,000 miles. If using the recommended fuels you should see no problems. Later RJD
 
This engine is direct injection, meaning the fuel is injected into the combustion chamber and not the port where fuel detergents do valve cleaning. Top tier fuel, injector cleaners etc will not touch the intake valves. PCV recycling oil and crankcase vapors through the intake will and those cause the carbon buildup. Years ago when we would do cams on the old 6.1 Hemi, there would literally be up to 1/2” of gooey oil mess buildup in the bottom of the aluminum intake from the PCV. That’s why we all used catch cans or oil separators to pull out as much oil vapor - mostly because that would cause knock. Now on these and all direct injection that cause buildup on intake valves. Using a high quality oil can reduce it (I’ll be using Valvoline Restore and Protect) but some engines have gone with dual injectors (port and direct) as solution to carbon buildup.
It can buildup in as little as 35,000 miles- depending on engine, oil, and change interval.

I AGREE WITH YOU! "IF" this stuff was needed, it would be installed at the factory since they are covering the warranty. I put this in the "gimmick" category, and there will be more coming.

I agree. Just another gimmick and we had a lot of them years ago. Later RJD

If it were needed for a stock engine, sure the factory would install it. But OEMs only build for stock boost, stock blow‑by, and emissions. Once you start running higher boost or pushing the HI6 past factory airflow levels, crankcase pressure goes up and the PCV system becomes a limitation.

That’s where a breather actually does something. It’s a supporting mod for builds that go beyond what the warranty covers (keyword here).

For a stock HO, yeah, it’s unnecessary. But once you’re tuning or increasing boost, it’s not a gimmick. It’s just a part the factory doesn’t include because they’re not designing the car for that level of pressure.

Then it may be worth the investment if your up grading your engine and racing. Later RJD
 
I will NOT be raising boost anytime soon because I want to keep my warranty. After reading a few horror stories on the HC boards, I'd much prefer Dodge fix my car than me in my driveway.
