703 injectors
What is so great about them? ive seen some info on this but trying to search on this sight is nearly imposable. Any info on them would be great. Right now I have a 89 MJ with the 4.0 I6. thanks

Very cool thank you. Now i have read in a few posts ive seen that they may calm down a rough idle and improve mpg. is any of that true? thank you

Yes it is true, the biggiest gains are from replacing dirty injectors, but the 4 hole design is better as stated above because better atomization there fore the fuel burns more completely.

Hell that would be nice. Im talking about my 89 MJ (comanche) and I get around 11 in the city :( I do however have a lead foot... Thank you for the info.

Oh im sorry I for got to ask, is it ok to buy them used? I read on here that you can find them cheep used (like 60 bucks) but am not sure about using used injectors. thanks

i went from 13 to 15mpg when i went from my stock injectors to my 99 LS1 injectors. also better throttle response, couldnt be happier

2mpg gain. Sweet. I could use a 2mpg gain. I just order a set. Can't wait to put them in.
Right now I am getting only 12~13mpg. My engine is either was running too cold, just replaced the thermostat from 180 to 195, or is running rich. All I got left to do to try and boost the economy is IAC and TPS after I get these injectors plugged in. |
Guys, just remember that results may vary. Get everything running in good order and clean, and you'll get good results. My XJ gives me about 22 mpg highway WHEN it's warm and after I've replaced my cracked header and kept the system clean. If you're getting 11 mpg, something is wrong with your rig, and the injectors aren't going to magically fix it unless the original problem is bad injectors.

thank you on the idea but I have changed every thing that could cause bad mpg. I mean it when I say im really heavy on the gas and I am also running 31" all terrains.

Yep :) I just PM'ed some body on here about a set they had for sale. Im looking into how to clean them once I get them. Thanks!
