Ah, congrats my friend
Let me know what you think of it.Figs
I have installed both systems, the Takeda on my car, and the Injen on a friends F. The Injen requires much more removal of stock components than the Takeda. IMHO, it would make more sense to install the Takeda first, do your tests, then remove the additional stock stuff, and install the Injen. Just a thought.

I was a little skeptical about purchasing the intake at first but I got an incredible deal on it so I couldn't resist. The construction is SUPERB, I didn't notice any flaws in the construction at all. The filter seemed to be of excellent construction as well. It's a dry cone filter, no oils at all. The replacement half box piece was also solid in its construction and fit perfectly into the other stock half of the box.
The bolts, screws and metal clippings were all spotless and matched (sometimes I've gotten screws that don't match and appeared to be just thrown together in the box). Everything was nicely packaged and the filter came in a completely separate box. There were no scratchy weld points or anything of the sort, everything seemed flawless. It took maybe 10 minutes to install (just like the Joe Z, it took no time at all). The box half was flawless as well, no mismatched edges or open gaps, it sealed very well with the other half of the stock box. The clips even matched up perfectly (I was skeptical about whether they were going to be off or not but surprisingly they were perfectly matched).
While I don't have that many miles with the intake on, you can definitely notice a slightly deeper sound from the intake about above 2,000 rpms. Below this, it sounds just like stock. When the secondary intake opens up at 3,600, it's not as noticeable as before although you can still hear it open up. From what I noticed, the power seemed much smoother across the RPM band. With the previous intake, you could definitely feel the car pull hard once the secondary intake opens, with this intake, the power seems to be available all across the power range. Basically the climb from the lower RPM range to the top RPM range appears smoother and the power is available more evenly across the band.
I plan on keeping the intake on for a little while longer, putting a few more miles on it and seeing how much I still like it after about a week or so.

That is a good suggestion Lou, The afe Takeda gets to me tomorrow and a the first dyno has been scheduled. I think the Gtech accellerometer tests should provide some insight as well...like peak G change if any. I mostly want to see if the low end HP is lost without the 2 stage, like when I dynoed the flap mod.
