Am I wrong?
Whether you think a aftermarket CAI is worth the $$ or not, is purely up to you. Jannetty also did a test with a drop in K&N and showed that zero HP gains. The K&N may filter better than the OEM filter but it doesn't free up HP. The HP gains aren't from a better filter, but a better design.
