KN 33-2374 Replacement Air Filter Review
I replaced the stock filter that comes with my 2007 Nissan Altima with this KN filter. My MPG had started to decline and I knew it was time for a new filter. Using this filter my MPG has gone back up and has even increased one or two MPG's. I wish I would've removed the stock filter the day I bought the car and put this in. Hopefully it lasts as long as they claim it does.

Saves gas, easy to install - G. Persico -
I was skeptical of claims that an air filter could save fuel. However in a carefully controlled test, using average driving conditions my vehicle is averaging 8/10 mile per gallon more. May not sound like much but it is 16 miles per tankful (about 3 round trips to work for me.) Engine seems to run free and climbs better.br /br /
