Hi again from Adam in NYC.

If I am going for more performance, I would put a better airfilter. In that mindset, I would put a snorkel, a precleaner, and a K & N large box filter.

As for the evidence, I haven't seen anybody take two identical vehicles that are benched to run identically the same(ala IROC) and then you put test filters in one, leave the other stock and then run them in identical tests.

That would be a great test.

I run a K&N, but I don't think it makes much of a difference. When you have one, just make sure you don't clean it too often (I think they recommend 50k miles), don't over-oil it, and make sure the oil saturates it (let it sit for a while) before putting it back in.
