They're orange or yellow colored. They have 4 very fine sprayers (pintles) vs our 1 inefficient 17lb pintle. They give noticable power, better idle, and better mileage. The 4.0tb will add more air to match the increased fuel and optimize everything.
These ones I am in the middle of the swap right now haha!

Can we just replace the injectors or is there more to it than that?

You can just swap injectors if you want. Takes an hour top even if you dont know what your doing. Just make sure they seat in the rail all the way

Haha, how big of a difference did it make for you .........and I have always ran 4.88s so I never really felt like I needed to upgrade any thing but I picked the tb/intake/injectors up from 91BoD on here who is parting his rig out for 55 bucks so I figure I would give it a shot and see what it does!

I'm on 4.10s but the idle was almost immediately smoother, highway speeds were easier and my mileage went From 15.5 to 17mpg. I tracked my mileage everytime on fill up when it was my dd

In there is the bosch part number.

Having said that i might be off !

this is the first I'm hearing of such an upgrade… anyone have a write up? my 4.56s can't even handle these 33s at highway speeds.
