amazon seems to be the cheapest place for the panel filter that goes in the stock airbox. If you are getting a cone filter I would suggest www.sbfilters.com over the KN.

I currently have the K&N 33-2375 panel filter in my V. I like it. Believe I paid $46 from Autozone for mine. I did notice a slight increase in both mpg, and throttle response off the line. Also, it's still subtle on sound without being too annoying.

I just want the panel filter. it should allow more air into the intake then stock filters so I should not have to push the gas as much to do 65MPH and the less I push the gas to do 65MPH the better MPG I should get.

so Autozone was $ 46.00 usd

any other place I can look?

hey thanks for the part number


amazon.com has one for 39.57 shipping 5.40
Total cost = 44.97

ill sell you mine for $20. just pay shipping
I really want a new one :blue flower: thanks for the offer! :thumb2:
did you notice any increase of MPG?

But keep in mind, more air = more fuel used.
uhmmmmmmmmm you made me do some re-search I have to re-oil the foam filter 13.75 filter care service kit same as a regular filter so those who say its cheaper in the long run never clean their k&N and there's a lot of dirty on the highway, summer pollen is bad too.. in the long run it could do more damage than good because of the oil so I guess the deal is off the table

I'm sorry for wasting the time, and I would like to thank you all for reading...
andriod did have a good point, it made me do more research and some people online say yes it works, some people say no, so it doesn't do anything, so I will probably see no difference or maybe a lil difference or none whatsoever
and the money that I could save on filters, I will spend it on cleaning the kandN and spend time cleaning then just dropping a clean filter in and be done.

Ok, it's 39.75 for a kn filter and can be reused during the lifetime/ownership of the car. $13.45 for the kn filter cleaning kit.

Disposable filters cost much less, 13.75 from the price you posted. You're required to replace it every 12 months and you plan to keep the car around 12 years (as example). Avg driver drives 12k miles a year so that would be 144k miles in 12 yrs.

13.75 (disposable air filter)x 12 (years)
= $165

$165 - $53.20 (kn filter & cleaning kit)
= $112 savings

Technically, you'll save money going the kn route. An entire kn filter cleaning kit 'should' last you until you part ways with the car. Alternately, you'll use more gas, but it's not going to be much to way more fiscally.

Recommended cleaning of the K&N is every 50,000 miles... that's on average about every 4-5 years depending on driving habits. Also, K&N guarantees their filters for 1 million miles if kept clean.

I've had oiled filters before. Never the panel filter, but always a cone. I myself will never go back, I'm sticking with paper filters. Never noticed any gain, a cleaning kit was only good for two cleanings. Well the oil they give will last forever but the actual cleaner was in short supply.

You can get air filters for really cheap. The WIX air filter from rockauto is only $4.99 and if you live close shipping is hardly nothing. I don't live close and I get my WIX air filter and WIX in cabin filter for $24 to my door. BTW WIX is way better quality then the OEM parts.

For me anyway it just makes more sense to swap out the filters every 30k miles then to clean the KN. Plus you're suppose to let the KN dry completely before oiling and reinstalling.

But KN and oiled filters been around forever and people do like them. I'm just saying they aren't for me anymore. Paper filters are just too much easier and cheaper when I crunch the numbers.

if I buy a K&N filter, and fill my tank and get the same MPG can I bring it back to the store and get a refund after about....lets say... a week ?

KN makes no guarantee to improving MPG

1.How will a K&N filter affect my vehicle's fuel economy?

There is a relationship between air filter restriction and mileage. The theory behind this is simple, the harder an engine has to work to suck air through the intake tubes and air filter, the more gas gets wasted in the process. Many K&N users report an increase in their fuel economy after beginning to use our air filters, as noted on our testimonial page. However, these experiences do not mean you will also experience a change in your mileage. We certainly understand why it is theoretically possible for a consumer to experience a mileage increase after installing a K&N air filter or intake system, however, we do not go so far as to make a general claim that our air filters and intake systems will provide an increase in mileage.

It is virtually impossible to make sweeping and general claims about mileage. Even the EPA fuel rating numbers for new cars are often not representative of the mileage you actually experience. There are many variables that affect mileage such as: tire inflation, the type of fuel, weather, elevation, the speed at which you drive, the gear in which you drive, the speed with which you accelerate, engine maintenance, excessive idling, cruise control, the grade of motor oil you use, and of course, the condition of your air filter. In short, mileage is complicated.

K&N filters are less restrictive than disposable paper or synthetic air filters and K&N Intake Systems are less restrictive than the factory installed air path. So K&N filter technology could be an important tool, when combined with other elements, to help keep mileage as high as possible.

Oh yeah, there's one more limitation imposed by science. If you take advantage of added power by driving more aggressively, you will reduce mileage. You cannot have your cake and eat it too.
They do make one for horsepower though but you must run the car on a dynometer.

K&N hereby warrants and guaranties to the original retail purchaser of any K&N air intake kit that the vehicle on which the air intake system is installed will gain an increase in horsepower, or K&N will refund the purchase price, including sales tax, to the retail purchaser, subject to the following terms and conditions:

* The K&N air intake system must have been properly installed on the vehicle in accordance with the included K&N instructions.
* The system must be the correct part number for the vehicle upon which it was installed.
* The vehicle must be in good running condition.
* The vehicle must undergo a dynamometer test both before and after the installation of the system, with no changes to the vehicle, except for the installation of the kit. The dyno tests must be performed by the same testing facility and must be performed within 30 days of one another and within 60 days of the date of purchase. The test results or work order for each test must reflect the name and address of the vehicle owner or operator having the test performed; the year, make, model and mileage of the vehicle being tested; and the horsepower results from both tests.
* If the dyno tests show that the vehicle did not gain an increase in horsepower, then the retail purchaser must return the complete air intake system to K&N in its original packaging, together with his or her proof of purchase, the ORIGINALS of the two dyno tests statement requesting a refund in accordance with our Horsepower Guarantee. Upon receipt of all of the foregoing, K&N will refund the full purchase price, including sales tax, to the original retail purchaser.
* This guaranty does not apply to any other costs incurred by the purchase, including, but not limited to, the dyno tests, parts and labor for the installation and removal of the air intake system, shipping costs, rental car, loss of use or incidental damages, if any, and K&N expressly disclaims any and all liability for same.
as far as bringing an item back to the store you bought it you would have to look at their return policy. I doubt they will take an item unless it was defective.

Don't need HP, with an extra 3hp, I still have to go 55MPH on 55MPH

KN makes no guarantee to improving MPG
that's what they claim,
They do not go so far as to make a general claim that their air filters and intake systems will provide an increase in MPG

those who see a MPG increase is because they went from a dirty Air filter to new air filter.


Good search, I no longer want a K&N to increase the MPG

All I have to do is:

Continue using the same fuel 89 octane.
Continue driving at the speed limit.
Continue driving at the highest gear to keep RPMs low.
Continue accelerating no higher than 3,000RPMs.
Continue changing the oil on time and keeping up with the maintenance.
Continue avoiding bumper to bumper traffic.
Continue driving at the speed limit at all times.
Continue using the same motor oil grade that NISSAN recommends

And final,
don't drive with a dirty air filter.

If I just keep doing what I'm doing, a K&N will not do anything to increase the MPG of my Versa :thumb2:

CASE CLOSED!!

:thumb2: what you said above is the only way to get the best mpg you can.

hi,

nissan recommends to change air filter every two years in the middle east. I bought my car second hand 2 years ago, with no history of previous air filter change.

so my air filter has an age of anywhere between 2 years to 5 years.
how can i determine if i need to change the air filter....

after following this, im not interested in K&N.
i would like OEM or any other branded air filter that is little better than the OEM at a reasonable price.

the two factors that affect me are
-a little better horsepower/acceleration
-silent car/engine....

is there any brand other than OEM, that can benefit me in the above two factors?

or else i would be happy going with OEM =)

Just a side note - using 89 octane fuel will not increase MPG. The octane rating has nothing to do with fuel effiecency. It is one of the biggest false beliefs and does nothing other than waste money.

I'd say change it every year. If you've never changed it, you'll be shocked how dirty it is:ihih: almost as bad as cabin filter! I used non-OEM, forget what brand.
