So positioning does make a difference, it just remains to be seen if this repositioning in the AFE is beneficial. In a similar fashion tube diameter is critical to a properly designed intake. If the diameter is too large for example the MAF once again cannot get a proper reading. That is why some el cheapo ebay intakes cause engine check lights to come on.

EDIT: And when im thinking about this again, isnt the STOCK MAF position exactly in the same location as on the aFe intake? (which means also the JWT intake should have the MAF at this exact offset but with the only difference that the stock MAF tunnel piping is slightly smaller (like 2.5" vs 3.0") diameter which i can imagine COULD reduce power slightly, but 15hp seams abit extreme IMO...)
STOCK MAF POSITION:
If you dont already know the stock location of the MAF, on the picture below its abit vauge but its just next to the yellow oil filler handle.
K&N Typhoon:
This is the intake (K&N Typhoon) i think has the best design, an im concidering to buy it today or tomorrow, it has almost identical design to the aFe and has a propper sealed airbox + a CAI ram that you can connect to the box witha water separator built in, and its half the price!! Nice real carbon air box to! K&N claim a 10.1 rwhp increase and has a beleavable dyno chart to back it up.
AFE INTAKE MAF POSITION:
As you can see, the MAF is EXACTLY at the same offset from the filter as with the stock setup (as well as all short ram intakes using the stock MAF tunnel...)

here we go... notice cold run in the middle... did that by letting the car sit 5-10 min. i drove the car about 40 min and then dynoed so it was hot and 94 degrees in the dyno room. now i gotta get a finalization on my baseline hp btw all dynos are different i have video of the runs ill try to get that on here also

I think the 21hp dyno that aFe did before must have been in ideal conditions and the dyno run with the stock for comparison in much worse.
Now i can safely order my Typhoon for half the afe price

I was looking at K&N dyno chart looks like they dynoed in the 9-10 AM in the morning. temps where much lower as shown on their dynometer. btw everyone in this shop complimented on the build quality of AFE. Anyway guys just thought id get this out there fast now i gotta work on a SRT-4 with a GT35R turbo straped to the motor

Soooo it might have some effect on the cars performance. but it does show improvement i really cant wait to see what happends on afe dyno. what everyone has to remember is all dynos are different the owner was saying his Dynojet always dynos 8hp less then anyone elses dyno and compared it with couple local guys shops. i have it all on video. Cars run different dureing different conditions and these conditions where pretty harsh since its HOT AS HELL in CA right now. In my opinion it did Pretty decent well know more tomarrow
Lets see tomorrow on the aFe dyno before we jump to any conclusions. But atleast so far nothing indicates that it would yeld the magic 21hp.

And yes you are right, some 15 degree diff to K&N's advantage, though as usual very hard to tell how much impact that has... But i dont see anything that would make the afe better then the Typhoon, rather the other way around, the afe dosent even have a sealed air box...
Looking forwards to tomorrows results from the same Dyno that you did the stock measurements on at afe.
