I would like to get stage 1 injectors for my 97, who should i get them from and what kind should i get?

 

go with brand new unmolested ACs if all your wanting is stage 1s

 

I went with Full Force stage 1's... Love em.

Rosewood or swamps is also a good choice

 

So I should get new ones and not have them modified?

What do the different codes mean like AC AB AA AD?

 

You can... My injectors were built and have the same warranty as a set of NEW injectors... and 700$ cheaper... Mine had all new internals and new nozzles put on...

Read that to answer your question about the different codes..

 

I also found Alliant injectors, are those any good?

 

Yes alliant are legitimate injectors...

 

Thanks for the injector info link, very helpful
