I’m sure this has been posted and answered before, and if it has feel free to direct me to that thread, but I have a 2011 with the flex fuel 4.7 V8 and I’m looking for information on any kind of engine mods that are available. Not necessarily looking for huge power adders, just looking for possibilities in terms of opening it up a bit, such as exhaust headers, intake manifolds, etc. it has 193,000 miles on it so I’m not looking for anything crazy, but it was my first vehicle years ago and I want to really have fun with it while it still runs.

 

Unfortunately, the 4.7 never got much love from the aftermarket performance companies, even when it was in production..... Headers should still be out there, and likely various tuners, but, I suspect that is about all you are going to find.

 

Honestly I’d be happy if I could find some headers. Every time I search for them all I can find is headers for the hemi. I have a k&n CAI and a family friend has a company that tunes mopar vehicles, I just need to find some good headers for it.

 

Summit seems to have some.... have to go thru the list and see which ones will work for ya.

 

Appreciate the link! Question is, most of those are listed for the 2002-2008 model years, would that fit in the 2011? Are the manifold layouts the same or did the change everything up between generations?

 

That, I don't know. Would have to look, and compare. So far as I know, the heads are the same, so, port spacing should be the same as well.
