Product Description
K&N's lifetime replacement air filters are designed to increase horsepower and acceleration while providing excellent filtration. The air filter is custom-designed to fit into your existing factory air box and the drop-in design means adding performance is simple. The unique design of the air filter features multiple layers of cotton fabric which capture airborne dirt particles. The filter is washable and reusable and can be easily cleaned and oiled. It lasts up to 50,000 miles before cleaning is needed.
I have been trying to find a cheaper alternative to the KN, but when I looked at the price, it was the same as buy 7 Walmart fram air filters. I off road so go through filters fast (I know you are not suppose to use KN off roading, but I do). Decided to buy the filter and never think about the filter again.
better gas mileage
since I've installed this filter my gas mileage around town has gone from around 18mpg to around 22mpg!and I've done nothing else that would have effected the mpg!
Didn't see any big differences
Changed from a paper air filter to the K&N. Didn't see any improvement in fuel milage nor experience any improvement in horse power. Hopefully I can save some money base on it being a re-usable filter.
03 g35
dropped this into my 03 g35 coupe with no problem. didnt notice any gains in power or mpg. excellent filter over oem.
Terrible experience
At first I was very excited by this filter. Even wrote a glowing review.
That was before the hot weather arrived, though whether this was a cause or coincidence is unknown. All I know is that, after 10 days, the Check Engine Light came on and the car refused to go above 2,500 RPM. Kept cutting out and jerking back and forth. Put the stock filter back in and the problem disappeared. Whether it is simply that Nissans/Infinitis with the V6 engine are particularly sensitive to fuel/air mixes, whether it's the weather or whether the design is bad, this filter did not work. I am returning it.
