i just got them back from f1, they have never been installed, they were tested and cleaned and balanced by f1 so they are like a fresh set of remand, they just have the flux 2 nozzles on them now as well, also installed by f1 diesel. I would like to stay right at 3k.. a set of these injectors go for 2500 plus 1200 or send your cores in.. and if you think about it you could send your injectors in and get them rebuilt and have new tips put on, and then sell them for 3k like i am. then you will basically be paying for a rebuild when its all said and done.. i would be willing to take your cores back and sell these for 2500 but then you would really be losing money..
The BBI's are great too, they are the best running injector i have ever heard or seen, they really did there research and took time developing them and they are really proving to be an amazing injector.. however they are a lot of $, if your looking to save a little cash then these ones that i am selling are high up there in quality so they are not a bad choice either..
