Well i would be inclined to trust K&N over Amazon as to whether a K&N Filter fits a certain car...
My Suzuki runs a BMW Z1 Pipercross panel, that 'doesn't fit' my car according to even pipercross Same goes for my MagnecorHT leads according to Magnecor lol. The only way to know 100% is to measure but if K&N says its suitable I'd trust that.
