PCV valve vent

Ok, I’m very close to running. But I see FFR wants you to change the pcv vent to before the throttle body. Why? Why can’t it vent like stock to the fitting behind the throttle body?

The PCV fresh air side located on the drivers side of the engine needs clean air. The connection on the cold air tube is filtered air. This is described as before the throttle body. After the throttle body would be pulling a vacuum. Without looking to verify on the Coyote, this pcv line is attached to the passenger side valve cover and pulls a vacuum from the intake tract. If you can post the quoted statement, it might be better discussed.

I spoke to FFR and they cleared it up. You describe it perfectly, the driver side connects to filtered metered air in front of TB and pass connects after. FFR instructs the way they do to build using their supplies coyote package which doesn’t have the factory pcv tube that I have. He said it was perfectly fine to connect mine as ford does. He also said they can both just be vented through filters to atmosphere.
