Who is using an oil deflector under the intake?

I wonder how many electric fan companies sponsored that show? I never trust data unless I know it's an unbiased source, OR I do it myself. Any of this could be argued to death. We could even argue the extra load the fans put on the alternator making it more difficult to turn and pulling more horse power that way. You do know that, right? As electrical load increases, the alternator sees more and more resistance to rotate. It's splitting hairs really. Just run whichever fan you want.
I agree that it's good to be wary about who you believe and where their interests lay, but I believe their numbers based off what I've seen from their programming and read from them in articles. They seem to know what their doing, and I have chosen to trust them. Whether or not other people do is up to them. I think a lot of this kind of stuff is splitting hairs, but that's the point. Trying to find how much of an improvement something makes and at what cost. And the extra resistance to turn the alternator will be nowhere near the resistance of a fan.
