1) any special tools required

2) from what I read I might as well upgarde to 4 hole?

3) where is the best place to get them

4) also read I can use mustang injectors?? are they cheaper

rig has 170K on the clock

1) any special tools required

No

2) from what I read I might as well upgarde to 4 hole?

Meh... I did. Didn't see any improvement

3) where is the best place to get them

I got mine on Fleabay

4) also read I can use mustang injectors?? are they cheaper

Dunno.

The most important thing when swapping injectors is getting the same flow rate.

I did mine a couple months ago on my 98' with 185k on the clock.
It was a 30 minute job, no special tools.

Definitely helped with starting crank time and idle quality, also seems to have better acceleration when pedaled hard.

Re: mpg increase ...... what's that ? it's a Jeep !

I bought these for the fact of supposed "flow match"
