Default Injector Swap

Not sure if this should be in the Advanced Tech section or not, but I would just like a quick cut and dry answer on this. I have a '98 XJ that I would like to swap the injectors out to get a little better gas mileage. What part number of injector could I just plug and play following the guide in the write up section? I just want to be able to run to O'Reilly's or AutoZone and grab them and put them in.

Go to Junk Yard and get them. Buying them brand new is not worth the little throttle response, or little (if none) MPG gain. JMO!

Junkyard. From a Dodge Neon. Or just check the for sale section for some 703s.

Honestly you might not even see better mileage. Mostly those who report better mileage just have dirty and gunked up OEM injectors. So in my opinion, unless you're also getting a bored throttle body, cold air intake, a header and swapping the newer intake manifold, just run some injector cleaner and be on your way
