Update: I have moved forward to a CAI. I prefer it because I noticed the slow take off during the summer months. I have had it on for several months and will keep it year round. There is a wow factor and plus I like that it cleans out the engine bay.
I used the same set up, but added a 6" pipe, one 45, and one 60. The order is 6, 4, 45, 60 from intake to filter. Also note that I used a silicone coupler to wedge into the hole in the wheel well because the coupler rings Spectre supplies are too big for that opening. This set up option was used because I had already trimmed my intake tube. I feel it is still superior because of the smooth pipe flow. I also noticed a slight increase of "driving feel" after switching. Maybe it is intake velocity? True a longer tube would increase velocity so perhaps that is it.
