The silicone couplings that go through the openings in the radiator support actually reduce the diameter compared to what the stock was drawing from.

Great feedback. Would have loved to know exactly what gains after the install. Can't really compare to the BMW's as their entire front configuration is different. Not sure if BMW's has a shroud on their filters to prevent hydro lock but that is restrictive. If that's the result they got in their BMWs then I feels sorry for them. As for my Z, there are noticeable gains and although purely subjective, would bet that I picked up additional hp in the mid to high teens.
This was my first mod and should therefore see the most gains. No exhaust upgrade until after 4 weeks. I would probably not see as much gain when that's installed. I noticed you added your Takeda last - after your berk hfc. At that point my understanding is you would see the least gain.
Additionally, the fact that Greddy is having AFE make these speaks to the quality of their product. Would have loved to see a cold air intake shootout between these products.
