I've had a look at some threads on non OE bonnet scoops, lots of them go back 2-4 years. I'm wondering what people think of them now 2-4 years later.

I can understand how a larger scoop will let in more air, but I'm keen to hear if people have noticed any real world difference?

And IC mounted fans. Does anyone know if they hinder air flow through the IC? My thinking is if they run slower than air being forced into the IC by the scoop, they may be more of a hinderance than a help?

Thanks for any help.
