I know a lot of people use them, I didn't feel my 2013 5.0 Coyote would need this. Just hit 126,800 miles Trucks running strong only things replaced in last 7 years is a Directional Module, Radiator Hose, and recently my Heater Blower Motor.

You guys use a Catch Can? Is it necessary with the Coyotes?

 

Not necessary.

 

When I first got my 2011 (used with 30K on it) I read a lot about the catch cans and was seriously considering getting one. After a while that sort of slipped off my radar.Now 5 years and 25K later (about 5K towing a 7,000# trailer) I have no issues and don't think I missed a thing by not installing one.
