Alliant Injectors in 02 F250
Injectors are fine. I might not have tackled the job without RiffRaff's instructions and support. Easy to understand, clear, concise, supporting photos... RiffRaff is more than just a parts seller!

Top Notch on new injectors
I had 354,800 miles on original stock injectors, they were a bit noisy and when winter came the last couple years it would have to warm up for 20 minutes before driving as a couple of the injectors were sticking. But once warmed up to operating temp it was fine.
The new injectors are awesome as she is really smooth now and much quieter, really runs like new. I have a fuel rail crossover and oil rail crossover from Clay, "and per Clay if you have this you do not need the long lead AE injector for the number 8 cylinder' You can have all AD injectors. You will not find a better price on new Alliant injectors, Clay has the best service as well. If your doing injector cups too look at my review under injector cups. -

Fuel mileage jumped 3 mpg
With 307k miles on original injectors I was having rough starts when oil was cold. Replaced all of the injectors and now it starts and runs like it's new. Fuel mileage also jumped 3 mpg back to 18.5 mpg hiway like it used to be!

Awsome product and the BEST PRICE anywhere.
bought 2 reman injectors in august and 1 gave out on cold mornings. Deciced to replace it with a new unit, and bought a total of 4 new Alliant units from Clay. As always his prices are the best around. Truck [2000 f250 7.3] runs better than ever, cold starts are like a gas engine. Took my truck on a 4 hour pull with mt 24' camp trailer and am very happy. Cant go wrong with NEW! Hopefully fuel mileage will be up too.
