Yes you are correct Blaq, it could. The reason for the design that way is Bc ADM tested this extensively and came to the conclusion that by the ECM reading the temp in the airbox, it accomplishes something far more important than the slight inaccurate IAT that might make your air fuel a tad off. And that finding was that
TIMING is worth way more power in the end result than air/fuel. Not to say that air/fuel is NOT important. It's just not MORE important. 1degree of timing pulled can be worth up to 10hp. Timing is pulled based off of intake temps!
So while all these so called comparison tests only give a snap shot at how each intake compares to each other with NO CHANGES TO TUNE OR CIRCUMSTANCES, you don't see the real picture as to how that same intake would perform in a multitude of situations with a corrected tune! You can have a CAI that is gaining you 18hp in perfect conditions.... But throw it in a hot environment, like say in the staging lanes or a stop light while driving on the street, and now that same intake is gonna make less hp due to TIMING being pulled!
This is where the difference in the temp that the ECM READS IS IMPORTANT! Less timing pulled = MORE HORSEPOWER! And if someone thinks that the Intake temps in their CAI are the exact same as ambient, under hot weather and stop and go traffic, then that person must believe that there engine puts off no heat and that their intake does not HEAT SOAK WHATSOEVER! Which is another reason I think ADM's combination is 1 step above someone like CAI inc. both have a tightly sealed well constructed box, so that in itself helps keep the temps cooler than an open lid style. But the MAF placement INSIDE THE SEALED BOX is gaining you TIMING.
Now, your tuner can adjust for the air/fuel and give you the best of both worlds! A well tuned ADM RACE CAI, is IMO the top of the food chain in OVERALL PERFORMANCE AND QUALITY! And it looks good too!
I will say that probably on a perfect weather day at the track, -1000 DA Vararam would hold it's own Bc I do like how it puts down power too. Just don't think it will in all other situations regardless of the addition to the heat shield. MAF is still gonna read what it reads and placement is the key.
