Topic has been discussed in previous thread. In the Search box at the top of the page type in "K&N air filters and it should come up.

I have heard of problems the oil in the filter causing mass air flow sensor failure. Could just be an over oil filter. Have no personal experiences with K&N.

I installed a K&N filter at 5,000 miles and its still there at 32000 miles. I did clean and oil it one time. My mileage, on the meter, shows about 24mpg. So i would say its worth the price. If you do not follow the cleaning instructions as printed you will have problems. You need to let the filter Air Dry after cleaing, then add the oil as stated. Do not over oil the filter and its good to go. Now to find comments on the GF Chip and if its worth the $69. :worship:

I just put ours in. Took a while to buy one but finally got it. Almost every vehilcle I've own has had one, and they are worth the $55. I've never had a problem and they always improve MPG even if only a fraction of a MPG, it will pay for it's self quickly.

For example, if you drive a vehicle that gets 17MPG, 12500Miles/yr, than your fuel cost is apporx $2500/yr, so even a 1% improvement (0.17mpg) would save you $25/yr in fuel, and not have to buy any more filters. so pays for itself.

The one thing is that you cant clean them too frequently, they do need some dirt to be efficient at filtering.

I'm seeing a 2 mpg performance gain with the K&N installed. I'm also seeing 2 mpg or a little bit more when towing our travel trailer. Check out this article on the topic http://bit.ly/mXiDtx

I used to swear by K&N filters and put them in all my cars. Then I got a check engine light in my Focus and traced it down to dirt and oil clogging up the MAF. I cleaned it up, took the K&N off and have driven 5 years since with no issues. If you're getting improved MPG, it's directly related to more dirt getting into your engine. More likely, you're not doing a fair test. My fuel economy improves 2-3mpg just based on the time of year with no changed to my car or driving.

I'm mean seriously, if the OEMs could get a 1% improvement in fuel economy for the price of a K&N filter, don't you think they'd do it?

They are not going to spend the money, paper filters are less than $1. they also have the warranty issue as the filters have a longer service life, and need to be maintained.

K&N would also have to compete against the likes of Honeywell, a multi billion dollar company with strong ties to the automotive industry.

As for your changes between seasons, thats completely normal due to gas mix and the fact that internal combustion engines perform less efficiently at lower temprtatures, higher humidity levels, very high temperatures etc.. For those us of us in the northen areas where winters are filled with snow, and frezzing temperatures, than you've heard of winter gas...Winter gas contains higher concentrations of isopropane, butane, ethanol and other additives that help with cold starting, converter burn off and prevent freezing of the fuel system, but it takes more gas to make the same amount of power. Therefore you use more of it.

Most people will see MPG changes that are attributed to ethanol content as well. Higher content of Ethanol doest burn well in standard calibration vehicles.

K&N filters do show an improvement, however small, with little or no loss in filtering capacity.

Same here. K&N Cold Air Induction. Haven't owned a vehicle in the last 20+ years that hasn't had at least a K&N filter. Wouldn't go any other way!!!!! Most vehicles complete CAI's
