What can I get out of my 3.7?

I'm researching mods for the 3.7 to get some more power out of it, but of course the reviews on certain things are 50/50. I'm thinking a throttle body spacer + cold air intake + hypertech max energy tuner.
What can I expect out of it? Would it be a waste of time and money? What parts if any do I NOT need, what parts should I get?
As we know the 3.7 is less than impressive stock, so I want to get more power, and better mpg. What do I need?
Little help here?!

intake, throttle body. throttle body spacers do nothing on our engines as its port fuel injected.

headers and a good catback.

and the hypertec.


also stop by my build for more ideas!

Re: What can I get out of my 3.7?

So if I were to look for headers, where would I look? And exhaust?

Re: What can I get out of my 3.7?

EBay has a seller for 3.7 liberty headers. Or just look up liberty jba headers. I got a custom catback built and welded for me out here in ca running 2.5in pipes with a 40 series Flowmaster muffler.

Basically what Alex said. EBay has the best price on headers. Summit racing has some decent catbacks for cheap or do what me and Alex did and go custom

Re: What can I get out of my 3.7?

Alright I'll look. So cold air intake and throttle body spacer don't do anything?

Yup tb spacer is crap if anything get a ported and polished tb from one of our members Connor I forget his screen name it improves throttle response. Get the headers, intake,exhaust, and the hypertech it helps a TON.

Ok. Thanks. I can't get everything at once so if there were 1 part you'd start with what would it be?

Re: What can I get out of my 3.7?

Oh and when I get headers, how much of a pain are they to install?
Sorry bout the rapid fire questions, this is my first jeep.
I'm used to working on an 88 Chevy suburban where even with a 350 there was enough room under the hood to have a party

Intake is a good start. I personally did the catback first then the intake....

The headers aren't too bad depending if your rwd like me and alex. Took me and a buddy 4.5 hrs to do. If your awd its gonna be a long one.


Personally also, if I did a engine swap, I'm going built 426 hemi based on the 6.1 block.

Don't worry about the questions. We are here for you!

Re: What can I get out of my 3.7?

Yea It's a 4wd.
Probably go with the intake, then when I get around to headers and exhaust I'll have it professionally installed.
Yea I'd love to swap the motor but I ain't got bread like that. Not yet
