33-2031-2 for Sentra 1.6 - The result is magnificent. I can feel the difference immediately after I put it in. The car also feels lighter and less sluggish during pickup. As for fuel consumption still untested as I have just used it for less than a week. Regards,

5 Star Review

Going into this product, I wasn't expecting a lot. But WOW! What a change. Who knew an air filter could provide such a change? I just put it into my 3.5L V6 2005 Nissan Altima, and I've noticed an increase in acceleration already. I have nothing on MPG yet, because I have just installed it. The engine has also developed this new sporty whine to it at around 4K+ RPMs. Loving this new air filter!

5 Star Review

Within the last month I purchased a K&N air filter for my 2005 Nissan Sentra 1.8s. After hearing about K&N for a few years I decidied to try it. Before with a paper filter I was averaging around 30 mpg in city and 36 mpg on the highway driving. In the three weeks since installing the filter I have noticed an increase of about 3 mpg. There is also a noticable improvement in throttle response and the car idles and shifts at lower rpms. Awesome product, telling my whole family and all my friends.
