they're not diesels, doesn't work that way.

if you have bad injectors, new 4 hole injectors may help with economy. there's a slight gain in lower rpm engine feel, if not a slight performance tick from better atomization. but otherwise, the computer is only going to allow as much fuel in as it needs to maintain stoich.

'97 zj 5.2, some stuff, some other suff, and some things that even work sometimes.

I did the 703 injector swap on my zj. overall smoother running and better throttle response. Haven't noticed any gain in power or mpg tho

I ended up going with these new Bosch 703's and hard to beat the price for new at $25/each for 6 with free shipping.

Don't you have to switch out the manifold injectors and the tailpipe injectors at the same time? That would be 16 total.
