I am new not he dodge seen and looking for any input of must do modifications or upgrades. I am looking for the basics and well worth the money spent at this time. I am looking at doing the oil filter bypass kit since I drive around 30-40k a year for work. I have a 2013 2500 mega cab. Hope that is enough info I pretty much just drive the dang thing and Dodge is still a little French to me at this time

Thanks G

 

Welcome to DTR, the very first thing you should do is the cabin air filter.https://www.dieseltruckresource.com/...d-t284729.html
