I have the AA Sport FMIC aswell. I had a very slight fitment issue where the cooler seemed to sit lower on one side than the other, but a little bit of cutting away the plastic soon sorted that.
I echo what the guy above said. I noticed an immediate difference in the car after install, simply put, it felt like the power was a much smoother delivery through the mid range.
I bought it directly from AA. Service was brilliant.
