Fiat and Cummins in court

Whether there's any risk of contamination using the Ram 2500/3500 capless system as-is is probably open to debate.

On the flipside, I would venture to say it would be pretty difficult to argue that an aftermarket cap is going to harm these trucks in any way.

For me, the negligible to 100 percent chance the aftermarket cap may offer some protection against a damaged engine was easily worth the $20 I spent.

Ding ding ding!!!
I bought the Billet cap and love it. I don't care if it's needed or not. Bought mine on Amazon and it's the best $20 I ever spent to not have to be concerned about it anymore.
