Default want to upgrade my injectors on my 89 RENIX

currently getting 15mpg average with 4.0, 3.55s and 32x11.5 BFGs which is not bad, but i also heard that if i upgrade the injectors i might see slight increase in MPG around town

going to the local Junk Yard and wondering what year/model/make injectors are a direct swap into my renix

i heard neons and some dodge caravans are a direct swap.. can some1 give me exact year and models i should be looking for?

and what is a good deal for 6 injectors from a JY?

You mentioned Dodge Caravan. I have injectors from a Caravan, #403. Rebuilt and flow matched.
They work great and I noticed an improvement in throttle response and start-up. Can't say on the mileage, going offroad ruins my numbers.
1996 XJ.

^^^ THIS! ^^^

The Volvo 746 injectors are the best match for the Renix 4.0's.

I got mine off EBay or contact Programbo here on this forum.
