I have an AEM Meth Injection Kit for sale. It is brand new still in the box. I also have the AEM filter kit to go with it. Retail was $438 for the Meth kit(30-3000) and $29 for the filter(30-3003). I will take $375 shipped.
I have a stage 2 kit I got last year for my previous car. Never installed it as I found the mustang shortly after receiving the kit. If you are still looking or interested, I can grab some pictures and get more details on the nozzles I have when I get home from work.
