Something else you should consider is an exhaust upgrade, i.e. get rid of the stock suitcase muffler and resonator so it's not whisper quiet anymore when running. I personally recommend a Jones Full Boar muffler as a replacement, but there are many others out there.
This won't technically add any performance, but it will make the car sound better, and as a result it will be more fun to drive IMHO.
Here's some links to posts I've made on this subject in the past:
If you search this site for posts by Nuke using the keyword JFB or Jones Full Boar, you will get many, many more hits on this topic.
: using that search above, you will run across a lot of posts on this site where I talk about upgrading the exhaust on my Challenger to use a JFB muffler. However, not all of the posts will apply to your situation. I had 2 different v6 Challengers and did the upgrade to both, but only one was a 3.5L like yours. As such, only those posts will truly apply to your situation. All the links I pasted above are either specific to my 2010 with the 3.5L or have information in them regarding the 3.5L, so you're good to go with those to start out.
: I just updated the post I referenced in my previous reply to include some external links to writeups on changing the spark plugs in the 3.5L I never did a write up on that, so I didn't have any ChallengerTalk links to paste in when I originally made that linked-to post. Now it points to others' write-ups or videos on the spark plug maintenance that exist on external sites.
