the material of the original one is feels more robust.

awesome fit and materials

I change my Oil every 5k Miles and will always be using these.(i have no way of comparing actual filtration levels compared to cheaper filters, but i watched videos of them dissecting these and the materials were excellent)

I only use full synthetic oil such as 15k protect."FYI, K&N customer service doesn't seem like they know about their production as well as they should because when I email and ask, the only respond was to follow manufacturer instruction

n’t go wrong with k&N
