How hard is it? What brand is better on stock engine other than k&n filter and muffler? I heard that they have to go in a certain way is that true or can you just screw them in like other vehicles?

 

I would get the same plugs that are in there, which are NGK plugs. Or if ya want get the NGK Tr-55's. It isn't that hard to replace them yours self, just take your ime, don't get into a rush. If your talking bout intake systems, any good name system will perform the same basically...

This is for the dodge correct? I have changed them on my other vehicles just not the dodge cuz I heard they go in a special way or some crap.
