If you'd taken the time to have a little read you'd realise the reason he can feel a difference is because he's swapped an original for a K&N, which has a greater air flow in comparison.
All you've done is swap the same one for a newer one so, although you were rather late doing it, you wouldn't have noticed too much of a difference.
