Max, nope! Yours is the best CAI I have seen to date on our XF's. Its intake origin is outside the engine bay (the area where the OEM tubes were?), its filtered, its tube diameter is larger than OEM (best I can discern) and both sides are (as best as possible) balanced (air masses merge approximately the same as the original, combining above the MAF to limit one sided airflow which might have skewered the metered flow in and throughout the cross-sectional area of the sensor).

You said the OEM temps at idle was the same vs your CAI (are those metal tubes or chromed plastic)? You mentioned they climbed into the 125 F range, was that with any type of tail breeze (it matters, engine heat easily flows forward into the OEM/CAI placed ducted area through the radiator/condensor coils and various gaping holes in that bulkhead if the breeze is towards the front)? I would expect that influx of (engine bay heated) air being sucked into those two intake points if the prevailing breeze carried that heat forward. Just a thought?

Finally, yes I keyed on your post. I did that because its rare to find that type of information posted unless someone asks. Yours is the example I liked most because of the information given, and the effectiveness of the design of actual CAI's. Not to mention (but I will anyway), its absolutely gorgeous looking! Clean, sharp, and in my opinion as pictured, totally 100% functional and a correct application of a CAI.
