Car Forum / Nissan / Nissan Cars / May 200807 Frontier Air Filter question
So, with gas prices the way they are, I looked at the air filter on my '07 Frontier XE. It looked a little dirty, so I thought I'd go and buy a new one. First, I went to an auto parts store. They didn't have them and couldn't find a part number. I went to my local Nissan dealer, and they said they don't have them in stock, but would order some. I thought that was a little strange for a dealer to not have air filters for an '07 model. I then went to another auto parts store and took a look at their manual for filters (air, oil, etc). It listed N/A for a Fram filter as well as STP for my model. But, they did have filters for an '07 with a 6 cyl. What gives with this filter for the '07 XE? > So, with gas prices the way they are, I looked at the air filter on > my '07 Frontier XE.

You could order one on line from http://www.courtesyparts.com/frontier/D40_maintenance.html. According to this web site the air filters have not changed since 2005 (same filters work for 2005-2008). Unless you filter was incredibly dirty, it is not going affect fuel economy by a measurable amount. Modern fuel injected engines are not affected by a dirty air filter like old carbureted engines were. A slightly more restrictive air filter is no different than a partially closed throttle.A dirty air filter can reduce maximum performance, but since you are looking for better gas mileage, I assume you are avoiding wide open throttle situations.

When you say, incredibly dirty, what do you mean exactly? Can't see any sunlight through it? Just trying to get an idea of what it would look like before replacing it.

In the old days they always said you should be able to see an illuminated light bulb though the filter element. I have a 2006 Frontier V-6. I just replace mine yearly (which for me is about every 24k miles). I've never pulled it out and thought it was too dirty to work a little longer, but I have never put the old one back either. On my farm, the tractors all have filter restriction detectors. In 25 years I've only had them indicate I needed to replace a filter once. I replace the tractor filters yearly. When I pull those filters out, they look a lot worse than any automotive filter I have ever changed, yet the one time when the filter restriction light was on, it was the back-up filter that need replacement (all my tractors have a main filter and a back-up filter - in theory the back-ups rarely need replacement, but they will eventually plug up, after the main filter has been replaced many times). My advice is to not exceed the Nissan Maintenance Schedule - it says to replace the engine air filter every 30k miles or 24 months. This applies to normal service (schedule 2) and severe service (schedule 1). However, the Nissan "Premium Care Plan" recommends an air filter replacement every 15K miles. Nissan recommends the "Premium Care Plan" "for owners who want the ultimate in preventative maintenance." I suppose if you want the "ultimate in preventative maintenance" you should replace the engine air filter every 15k miles. Personally, I like the one year schedule I am on, easier to remember and I am not likely to exceed the severe service schedule of 30k miles doing a yearly change. Nissan recommends replacing the cabin air filter more often than the engine air filter. I've replaced those twice now and they don't look near as dirty as shown in the Nissan guide (see http://www.nissanusa.com/pdf/owning/vehicle_care/2007_Nissan_Service_Maintenance _Guide.pdf , page 18). On the other hand, I don't think they work worth a d&*n judging by the amount of dust in my truck and the fact that I always have an allergy attack when I drive through a particular area (a swamp with some bush that drives me nuts).
