I just wanna know which neon injectors people are using to get better mpg? How much better you guys are getting? My engine is stock but think bout some basic upgrades to improve mpg, any other ideas?
I am installing a 3.5 inch RE lift and some 31's what kinda mpg should I expect?

The neon injectors you want are the 2.4L injectors from the 95-97 Neon. There are also many other vehicles manufactured my Mopar that you can use the injectors from. Also, you can use the Ford style injectors off the 5.0 Explorer and Mountaineers. All of those will work. Next time use the search unfction located at the top of your screen. Here is all the info you need in post 112 https://www.cherokeeforum.com/f2/mor...-13848/index8/ . Go to the last page towards the bottom for all of the Mopar vehicles.

For a 1996 with 4.0 you would want to run the 0 280 155 703 neon injectors.
In my 1999 i run the later model neon injectors (0 280 155 784)
I have a much smoother idle, throttle response has improved greatly, I have not yet documented fuel mileage yet. Being winter its hard to get a good reading with all the warming up i let the car do before driving.

I believe those are the 24 lb injectors and those won't work for stock motors. If it was a stroker, they would be fine. You need the yellow 19 lb stick style injectors for a stock motor. In the link I posed earlier, there is a list of all the Ford injectors you can use along with all the Mopar injectors on page 13. Injectors from a 5.0L Explorer or Mountaineer are the ones you want if you're going with Ford style injectors. Just look around eBay and wait till a cheap set pops up. I picked up a mint set today for $25.

After reading the injector threads, I was at first confused, but after re-reading I found what was really needed. The 2.4L Neon injectors or the Ford 5.0 Explorer injectors. I went with some Ford 5.0 injectors out of a low mileage Explorer and they are in mint condition. Doesn't even look like the o-rings need replacement. And for $25, I couldn't pass it up. I kinda wanna see what happens to all the people just running injectors because they fit. I assume the O2 sensors crap out before anything else along with bad gas mileage.
