How often do you all recommend to change your air filter?

Just buy a K&N drop in filter or a fram air hog from AutoZone or Pep Boys. All you have to do is clean and re-oil them every 60,000 miles or so. They also give better breathability. I have Fram Air Hog, it works great.

So you saying not to buy the facotry nissan air filter?

the K&N or Fram Air is better than the stock air filter, allows more air plus you can clean it so it pays for itself over time.

I'd get a K&N and clean it every 3-4 months, or just inspect it from time to time, if it looks dirty clean it.

~every 15,000 miles with a OEM filter

I disagree with the K&N recommendation. The OEM air filter is good -- just use it. If you just follow the factory service manual, you'll be fine. They recommend changing the air filter every 24 months or 30,000 miles. If you operate your car in dusty conditions, you'll have to change it more often than that.

If you want to be really picky and pamper your car, you can change it twice as often. It's just money.

Just because a part is marketed as an "upgrade" does not mean that it's really an improvement. The factory recommendations are worth following unless you have a truly compelling reason not to follow them.

I believe an OEM type filter is every 15,000 miles or so. Rule of thumb is to inspect it by looking up at the sun with it and seeing if you can see light coming through, if you do its okay. If not get a new one.

If you look at the Factory Service Manual, page MA-6 (Schedule 1) or MA-7 (Schedule 2), you'll find that the recommendation is indeed 24 months or 30,000 miles, with a note that if operated in mainly dusty conditions, it may need more frequent maintenance.

Why are we even debating something like this, anyway?

the best filter for your car is a dirty one. it will rob performance, but will not allow more dirt to come in since its cloged. but anyway i got a k+n so i clean it every 6 months.

And whats your point? Not all filters are created equal, K&N's take longer intervals to clean, cheap filters probably wont even show a spec of dirt since they let all dirt pass through why not just check it?
... and no ones debating about it.

oh and Good job changing your post up above to make it look like you were right.

Filters are so cheap anyway, why would you wait that far and just not check it? You can look at it in another way and buy a K&N which is going to last the life of your car and just clean it out every 50,000 miles.

A service tech said that the K&N was a waste because the max measures the amount of air coming in and adjusts accordingly. I don't know if that is bs or not though. I didn't have time to make him explain himself.
Even if it did allow some extra air I wonder if it actually makes a difference in hp or anything. I would bet not. You do save money over time with a K&N though. I don't think that is worth the risk of over oiling it and ruining your MAF or under-oiling it and letting in contaminants though. I just use a wix filter that I change every 10000-15000 miles.

The MAF does measure the amount of air coming in and adjust for it. However this is all the more reason to get a K&N high-flow intake, which allows more air to pass through the MAF and into the intake plenum. I cannot honestly say that there are any performance gains to slapping in a K&N panel filter, but I gaurantee you if you buy one and compare it to the OEM one you will see a quality difference. Not to mention they have a 1,000,000 mile warranty and are reuseable, so you don't have to waste money on new OEM filters in the long run.

My point is the OEM filter will do a fine job, and the FSM gives you a recommendation from the people who designed the car, so that should carry some weight. There's no point in overmaintaining the car, it's just a waste of time and money.

The K&N filters flow better in part because they also let more dirt through into your engine. The paper filters are not that restrictive and the difference in power you might get from the K&N is not enough to matter. People are just falling for marketing and hype.

I changed my post 3 minutes after I wrote it to correct a spelling error. That was around 30 minutes before you posted anything so I don't know why you say I changed it to look like I was right. See for yourself.

If I challenge something you post, please try not to take it personally. It's not intended that way. Sorry about using the , I just meant the original poster was asking a question that the owner's manual already answered, so it seemed kind of pointless to debate.
