X2? I have a 97 with the iL6. Im pretty sure all 4.0 injectors were all interchangeable between years 91 or 2 till 99. Im not positive tho so anyone who can specify would be appreciated

Alright so I found out that if you want the neon injectors they are the *703's you need and multiple write ups suggest that if you have 95 or prior year you should upgrade the fuel pressure regulator as well

No need to change the pressure regulator, just the injectors.

+2. They 703s have the same flow rate as the stockers. No need to change the regulator.

Would a set of new injectors and a regulator help make my exhaust smell a little less rich, or is that just how the computer tells it to run? Seriously, I haven't smelled exhaust this rich on a fuel injected catalyst motor... ever

I'm going with Mustang 5.0 Injectors, near bolt in (have 4 holes instead of 1, more fuel, better spray)

So if the 703's have the same fuel flow then what's the benefit of using them?

The stock injectors have one hole and the 703s have a 4 hole tip. Supposedly better flow for atomization resulting in smoother idle and better throttle response.

Here's the lowdown. If you have a pre-96 you can use 703's and it's plug-n-play. 97 and later use 783's also from neons. No real hp gain. Just milage and smoother running.
