Nasty old fuel filter!!
Nasty old fuel filter!!
Had it changed yesterday, the stuff coming out was pretty turbid.
After changing it, i feel a significant increase in power, response.
People, if you haven't changed yours in a while, DO IT!!!!

I change mine @ least 2 x's a year...
Another benefit of changing the filter regularly is that you can get the damn hoses to come off. Every 4th gen I've had has had a fuel filter that was several years old...and I had to cut off the bottom fuel hose and buy a new one. 
At least fuel hose is cheap.

Glad to see more people are starting to do this. About 2 months ago I started a thread to troubleshoot why I was getting such crappy fuel economy (I was getting about 18 mpg driving conservatively, terrible). I tried literally a dozen different solutions to try and fix the problem, completely overlooking something as simple as a fuel filter. So then I finally got to my fuel filter off and took a good look at it. It looked pretty old, and it said made in Japan on it, where my maxima was made. I'm pretty sure it was the original fuel filter, also because I have service records going back to 70k and none of them list fuel filter change. When I turned it over a bunch of orange and brown crap came out, further supporting my opinion that it was the original filter. I installed a new filter, and the difference in my car's performance was unbelievable. It was a lot more responsive, faster, and quicker to shift. After calculating my fuel economy, my average was back up to an expected 24 mpg. It crazy how the smallest simplest things can greatly affect your car's performance.

now on! Definitely is not a placebo.
Yup. Heck, you can even change it every 50K miles. Performance may go down, but not by much.
Fuel filters that have been severely neglected, like 100K miles then change, are the ones that cause severe trouble.

It costs like ~$11 for a fuel filter. You spend more on a car wash lol. If you are unsure how long its been there, just change it. That's what I did and my car starts with a force I've never seen before. As I think I said before, I can pull out without setting the gas and the RPMs stay around 1000. I kept the original tubing that connects to the base and top of the filter although it was a PITA to remove.
Here's a description of the Hastings fuel filter I bought and red highlighted text swayed my decision to choose this filter:

LOL! Hey, it was still functioning although I am about to create a new thread for an idling issue. Also for the rest of you, if your fuel filter has the yellow top and has rubber pads on it, that is your original filter and after 13+ years of the 4th gen, its time to replace.
