Drivetrain a Couple of Thoughts on ICs...
You'll be one of the first. It should work quite well.
I think they did a pretty good job with the space they had to work with. The stock unit flows and recovers very well.

Heres my take on on it.
I see it differently
Gary and I were talking about the install and he was asking about what to expect.... That got me thinking again.... Seems there are three things to look for with an IC....
1) High speed high power operation. This would be the road racer......
DFIC ,needs high speed to push the air through all that thickness
Here I think the vertical units are at their happiest - Here you want freer flow, at high speeds you are getting plenty of air to flow thru the IC.
2) Heat soak rejection/recovery. This is for the street driver......
GP, ALTA classic ,thin ,top mounted ,taking off from a stop light with low cooling air flow ,the cooling air will get through them easier and sooner
Here the DFIC seems to stands out its vertical designs seems to dump heat soak sooner than the horizontal units. It appears to work w/ less air do to the straight line air travel.
3) Throttle response. This is for everyone.....
smooth plastic tube
Depending on how you weight the various aspects, you may get a very different answer as to what is "best"...
As far as rating ,with all regards including costs I think probably a clean stock IC is best
No doubt the stock IC has set a high bar - aftermarkets are at best
able to make slight improvements in only one direction - either thermal efficiency or freer flow but not both.

Some more questions for you all....

What role does INTERNAL pressure drop figure in your estimates?

Heat soak is s function of a couple of things. How much heat gets to the IC, what it's thermal mass is, and how fast it can shed the heat.
3) Throttle response. This is for everyone.....

Interesting approach!
But then, different ICs have different "feels" on this one.
