Yes you got ripped off. But that was when you bought the AEM setup for an XJ. Who cares what color the filter is.

Also, last I checked a CAI on an XJ isn't stupid. I know someone did a test and saw an improvement. Nothing "OMG GLORIOUS" amazing, but a gain nonetheless.

As long as it is well insulated from the underhood temps, then a CAI will work on an XJ.

Thought about just calling AEM? Where did you buy it from that makes you think it's not legit?

I got word back from AEM and they said the new red one's are identical in flow and filtration to the old grey one's, but that if I still wanted a grey one to check back at a later date. The grey one's part number ends in BF (brute force?) and the others end in DK. According to the email the screen mesh is there on the red one's to straighten airflow and strengthen the filter.

What kit is insulated well? The only way to do that would be to totally isolate that part of the engine bay and route air from outside to the intake. A little sheet metal shield won't do that.
