"the k&n filter fits great & i can feel a little differance when i push the accelerator. ive also gained 1 1/2 more mpg ,another plus. it is a bit pricey but lasting a lifetime & some savingings @ the pump helps defray the costs,& the extra little performance doesnt hurt my feelings." —John T from Springfield , WV bought a K&N Air Filters for a 2007 Ford Focus, 3.7L 5 cyl. engine.
