Great product!
Style: Two Pieces
These were a perfect fit for my MB and very easy to install. Great value for the money. They should last given the way they were built.

Exact fit, no trimming needed
Style: One Piece
Ordered this for my Ford F-150 and it dropped right into the airbox perfectly — same dimensions as the OEM filter, same end seals, same fit. No gaps, no air bypass around the edges. Clean swap in under five minutes. Engine runs smooth and the price is unbeatable.
