Yeah, for the 6i, any CAI or any short ram has about the same-ish improvement, except K&N which is just weak.
I've had my AEM for about 3 months nw and I've had no CEL and I have a 6s. Like I said, if you're really anal about every little HP and you can deal with a CEL being on all the time, Injen is the way to go. Just my opinion though.
