I'm slowly replacing everything. The current injectors are working ok but have cracks in the body from age which concerns me. Is there an upgrade with a better spray pattern for these vehicles?

 

I used some 24lb ford injectors. Had to modify the seat, they've been working good for a few years so far.

Pretty much the same dimensions.

Had to modify this plastic to fit the intake. Just a small file and shaved them down.

 

I recommend K suspension 4 hole injectors.

 

I have the same with the viper coil mod. Gained 3 mpg.

 

I'd be curious to know if the mpg gain was due to partially clogged original injectors or whether the 4-hole spray pattern truly makes a difference.

 

“784” injectors are what people commonly swap into the 99+ models. That is the last 3 numbers of the Bosch injectors part number.

Note they flow ~7% more fuel than stock so you will be about 7% richer under moderate acceleration to WOT. There is some debate about if it’s actually a good idea to use them long term.

I’ve had them for years but only recently considered how they affect the operation of the system.

 

If I remember I used some 12 hole injectors...can't remember from what though but was from ebay.

Well got looking and used Bosch Bosch 0280156161 12hole from seller Dimar MotorSports

 

Another satisfied 12 hole 161 injector user.
Easier starts, smoother running at all RPM and better throttle response. Mines a '95 4.0

 

Ok thanks. $179.00 seems reasonable

 

Installed those today. Runs good. Thanks!

 

Bosch 4 hole. There have been several different people on the different jeep sites sell sets they get from junkyard donor vehicles. I bought 6 sets at $30 each
