Love this filter! It gives the car a nicer sound and a little better performance. I have these filters on all my cars.

Muy contento con los resultados, al instalarlo se noto de inmediato el cambio, un sonido más rudo cuando acelera, muy bien a calidad comparando con los filtros comunes, al acelerar el auto se siente muy ligero, recomendable , espero se pudiera subir videos para que vieran y escucharan el cambio.

I got my K&N air filter around 4 days after I ordered it. It was definitely cheaper than the local Auto parts store! I think I can feel a slight bump in acceleration but I haven't checked my gas mileage yet. I'm sure it's better. I love the filter! It fit right in no sweat. I can tell it gave it a little more air flow.
