K&N Performance High-Flow Engine Air Filter: Washable, Multi-Layer Protection, Engineered to Boost Horsepower, 33-2031-2

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,

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!

Dear K&N,  I have a 2002 Nissan Maxima GLE.  Before replacing my air filter with your product, I was averaging about 23 to 24 mpg and getting about 330 to 335 miles on a full tank of fuel.  After installing your air filter, I am now getting 27 mpg and a minimum of 400 miles on a tank! My fuel economy has improved by almost 20 percent! Thanks for making a SUPERB product! Sincerely Yours,

I own a 2003 Nissan 350z and dropped in a short ram K&N air intake and it gave me lots of power and it is also good on gas. I also noticed that it sounds way much better when I step on the peddle. It just makes me satistied that k&n can make an air filter and intake that will give performance to your car or truck. I recomend this to everybody!

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.

We recently purchased a drop in KN Air Filter. The goal was maybe increased performance, gas mileage and saving money on the long run with a reusable filter. Also ease of used and maintenance.

Product works as advertised. I didn't get a noticeable increase in power, but my throttle response and idle is better, and my engine revs faster and higher

I placed this filter in my V-6 Nissan Altima to reduce replacement cost. I got in return better efficience on gas mileage with better acceleration. I am now average 30 mpg from 26 mpg.

Hi, Put a K & N filter in my wife's 2000 Nissan Xterra with 3.3 liter engine and went from 15 mpg to 18 mpg. Thanks,

Excellent product!!! I can really feel the difference in performance between the K&N filter and the stock filter.
