AMS only makes one core for our cars. I got one on sale and paid a little over 730 delivered. So this is a great deal.
Its technically 6 inches.
Fitment is spot on. Did require me to shave a 1/4 plastic off inner plastic shroud but you cant tell it was shaved. Stock intercooler can go back on later and you will never be able to tell it was removed.
Great FMIC. I love mine.
