Also - materials... polished aluminum (77 series)=worst. Plastic = better. Polished SS=best. And none of it matters at speed, where the IAT's are very similar.
And despite urban legend - K&N did not do enough R&D on these trucks. Which is why AF1's blow them right out of the water. Talk to Mike Troyer, ok?
