It's a perfect fit. Just installed 3 days ago on my 5yr old Nissan Grand Livina 1.8L. Noticed a smoother and quicker throttle response as compared to the other (relatively newly replaced) paper filter. I had the new paper filter for only a few days prior to installing this K&N, so the difference I noticed now is not placebo. I am happy with my purchase! From where I live (Philippines) a dusty place, never again I will spend 1,200 pesos ($27 USD) a year to replace a paper filter.
