OK, but realistically, If all your doing this for is fuel economy, its a waste of time and money for you. With a CAI you may get 1-2 mpg better. Now, figuring the miles you gave above( 25000 left on warranty, about one year) and IF you are getting 40mpg now, that would be 625 gallons of gas. Getting 42mpg would be 595 gallons for that same 25k miles. So 30 gallons per year. Or at 3.50 per gallon thats 105.00 dollars per year, or 4 years just to recoup your investment before you start saving money. Granted, higher gas prices bring that time down. But if fuel economy is all your after, alter your driving or look at the whole picture with other stuff, like bumping tire pressure or lowering weight etc. CAI is more of a performance mod to help the engine breath better at high RPM, with slightly better mileage as a bonus. I've heard as many bad things about k/N filters as I have good, but something makes me think the bad is from over oiling the filter.....

Your input made me search some more. It's difficult to get the facts. K&N claim it is not their filter that cause problems to the MAF .
And other "specialists" beleive the oposit.

I already have the stock shape K&N filter coming in. I may use that filter for few months to see by myself.. but i may end up returning to disposable air filters.
I was told that those sensors provided with your stock intake were quite expensive parts to buy if they were to be damaged.

Because i live in a winter area...and we get tons of snow, dirts, ice, salt... where temperature can reach -15 Fahrenheit sometime (that's minus fifteen).. i hope those oiled air filter won't hurt the engine

If anyone had any bad experience with K&N filter during winter and heavy dirt, feel free to comment
