i've found them incredibly difficult to find. I managed to find only one car with the 703s last time.

Make sure you give them a good cleaning before installing them.

I went thru 10-12 cars and was about to give up when I found a set. Since that gave me 4, I kept looking and found several more sets. It's not just neons. Check the chart I posted previously in this thread.

i know. The junkyard i went to had tons of chryslers and dodges on that list. I went through every single one - only one had 703s.

Luck of the draw i guess. I'll check another JY next time

Definitely gonna watch the MPG for improvement. Will post up what I get.
Put a 99+ intake on there and you will really notice a difference.

I dont think so..IIRC in 99/00 they switched to the EV6 style plugs..so you would either have to get some female connectors from a Doner vehicle and repin or...buy adapter's

The injectors are also different for a 1999-2001 Cherokee.
87-98 *703 injectors
99-01 *784 injectors

This chart should help:
Good to hear the 4ever banger included for once

IF all it is is EV-6 connectors, I have EV-1's connectors.

I'd wonder if the 2000 would be an updated injector anyways
