Ok...here it is.

Stock or close to it...or on something bigger than a 3.4"...you want a fenderwell or something getting as cold of air as possible. When your at a 3.4" or lower...and your blower is just gettin' stupid hot...it doesn't matter about intake placement, hell even the IAT doesn't matter since 90% of people just zip tie it to the TB bracket. A filter bolted to the TB is the best bet. I'll take a picture of my engine bay lunch and post it in here...just for reference.
