Thoughts

I've often wondered about the differences between the intake designs of the C4 vs C5/6. Stock they are similar with the C5/6 having more area/volume behind the filter. Most of the aftermarket versions are more of a straight through design which I would think would be less restrictive than the acute bending design of stock. Interesting.
