I had a yj with a 4 cyl, 4.10s, 5 speed, and 35s. 5th gear was useless. I had a fuel inj start leaking and had been reading around and found that the 5.0 ford injectors could be swapped with the 4 cyl injectors. They were a 4 hole injector compared to a 2 hole injector. I noticed a slight increase in mileage, it also held hills better. I got these free from a buddy though as he was upgrading the ones in his mustang.[/QUOTE]

I can second this I went with Bosch three or four hole injectors in my 02 TJ. Sorry I can't remember exactly which one but I notice a good increase in power and ability to keep mph up hills... I'm sure there was a small increase in mpg but I didn't keep track at the time
