what injectors should I go with?

[FRAM]

Or try fiveomotorsport- I'm running Ford 19lb injectors in my 1990 4.0 XJ.
Service was good: fast, exactly as stated. http://www.fiveomotorsport.com/
They run great, with no leaks. My stockers were leaking at the seam on the injector body.

Does this improve fuel economy?

wow! i got mine off of a local classifieds web site (craigslist) for 20 bones used. cleaned them up, installed, and ran injector cleaner through the system. been a month and great results. not sure about gas milage but i know its a bit more responsive to the pedal. )

19lb injectors are standard ....only reason to go higher is if you mod the engine...cam....racing pistons n stuff like that that increases performance.If you got to the web site they list ALL applications for all JEEP engines....from OEM type injectors to high performance engines.....
