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.

Fit in my vehicle, arrived on time and cheaper option than buying regular filter. Thanks K&N for open direct purchase option.

I reset my average MPG display when I installed these a few weeks ago, and I'm tracking about 1MPG better than I have since I bought the car. I'm very pleased with them.

Car engine is quieter, and has more pep since air filter was installed.

Bought the filters for my 2014 q50 awd sport. Best decision I've made & I have no regrets. Only thing is you have to really open your car up to get it used to the extra air flow then you will see the Lil boost in throttle time. Excellent product. All I have to do now is do some research on their cold intakes for my car.
