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.

Great plug
Style: Single
My car goes through these every 30,000 miles or so. But fantastic plug all around. Performs flawlessly even at almost 9000 rpm.
