PCV and catch cans

[73440]

Im assuming the open system would keep the fuel and the engine insides the cleanest, maybe not the engine bay though.

Just need one catch can with a breather for air in should be sufficient. They just want to sell two to increase sale.

Very first Mod I did when I had my SRT was put a catch can on it. Was amazing the amount of residue it caught trying to be pumped back into the engine.

Did same for my 2012 and added one to my 73. Just don't forget to empty it each time you check oil level.
