Denso 12582704 Injectors, who's done it.

looking for feedback from guys who have swaped to the GM 12 hole injector. not sure if they would fit the 5.7 but they will the 4.7 and 3.7

my 3.7 has a cylinder 3 misfire only at idle. new plugs and coils. so im going to swap all the injectors as well.

really thinking of these. just can't find anywhere with a flow matched set of 6 or 8.

well ive done it now, works great, 100% direct swap. i did not need to modify anything on my 2008 v6. so far im seeing a steady 2mpg improvement but this is VS the old wore out injectors so idk. truck is for sure more responsive and throws no codes.

I have just added an '02 Durango with a 4.7 to the corral. It was parked in '09 due to a bad brake caliper. Unfortunately, the fuel system is toast due to 11 years of sitting with crap Minnesota corn gas.
Are you still satisfied with the 12 hole Denso injectors?

sorry, never got a notification about the reply. yes absolutely glad i did the swap. though i dont know if new oem would the the same. the ones i removed were original with lots of use. so not really apples to apples but feel 100% improved with much better mpg. Its actually gotten better as the computer (seemed to) learned the difference.

tomorrow im going from 3.55 to 4.56 gear in the rear. that will make a big difference as well.
