That's how I got mine... the guy said he's going to be in the market for a new Jeep soon, so I asked why he was wanting to sell it... then he reminded me that the one he has is for the 2007-2010 Jeep and he'll be getting a new 2012 or 13, so I suspect it's the same with most of these others.

I sold mine because I didn't notice a difference at all. It would ping no matter what fuel I put in and no increase in mpg/power on the butt dyno.
