I always read that cold air intakes will all give you about the same horsepower so just choose the one you like and be done with it, which is logical thinking....with the LS1, since there all the same design (A lid). What about on an LT1 F-body though, The designs vary so much. I mean the SLP one has two different filters, which to me would seem like it is more optomized for low rpm breathing or upper rpm breathing (not sure which one). Then theres the K&N, Moroso, and G2, which are all unique in their own way. Thats probably not even half of them either. So what is the most effective one, Is there a most effective one, and which one do you guys use and would you recommend it?
