| How many of you guys have one of these with a stock setup? Would you recomend it? |

| I had one before I switched to the JWT cone intake. My opinion with the K&N panel filter is that it won't give you any more power, but the advantage comes from the fact you can clean it and reuse it instead of replacing it. It will take a few cycles of that to recover the cost difference though. |

| I used to have it in the Murano. Switched back to paper one. Too much hassle with cleaning the K&N filter, too messy. And there is really no advantage in anything... |

I dunno. I dropped one in last year and noticed a difference (it took the engine sensors about 5 minutes to get used to it). A BIT more pep, better fuel ecomomy (I'm averaging 21 MPG vs 19 prior). And of course, the fact that you're not cluttering up landfills w/ paper airfilters.
The cleaning isn't that bad. I do it 2X per year; always while detailing Mo - so by the time I'm done, it's clean and dry.
It's all perspective. Someone suggested that I drop a cone K&N in - but I really don't see the need.... |

You are claiming a 10.5% increase in fuel efficiency? That is a highly dubious claim.

Its possible the old filter was dirty and the increased fuel economy is the result of just having a clean more free flowing filter.
I had the K&N panel filter briefly and did not notice any mileage improvement, but there wasn't a decrease either. |

| As I mentioned I did use the K&N filter for probably 20k miles. I did not, I repeat I did not notice any difference in performance nor mileage... |

I'm just going by what the fuel economy read out said on Mo. I was pleased.
I didn't do the change for the fuel/perfomance reasons though. It was strictly a landfill thing. What I experienced was just a benefit IMO. |

| I put mine is about 3 months ago and I did notice immediately that the MO breathed a little easier. The previous filter was not that dirty but K&N filter did make my MO a little peppier and slightly more responsive. I don't mind the cleaning process; I may even get a second filter so I don't have to wait for the first to dry. I'm not looking for a performance improvement; but any help in keep the MO breathing happily is good for me:D |

Actually, you are not supposed to clean filter for at least 50K miles. They are supposed to work better as they get dustier.
We did not notice much difference with the switch. Maybe slightly peppier. Darrell. |

dborla01 -
When I first got my MO a neighbor tried to convince me to go with the K&N filter. He, too, made the claim that the filter is supposed to work better as it gets more dirty. I'll ask you the same question I asked him... Does this mean the clean filter is letting small particles pass through to the engine that would otherwise be trapped in the filter once it is used more? Hmmm.

Picky picky picky.....:D |

Actually I do think the K&N lets a little more junk through than a brand new paper filter. But after you put some miles on it the oil in the K&N is thoroughly distributed and any dirt trapped in there just helps to block more dirt, which I assume is true with the paper filter as well. The only difference is that the K&N supposedly flows better, so even if its partially clogged it will flow better than a similar clogged paper filter.
I've put 100,000 miles on various cars with a K&N filter and never had any issues though. Always used Mobil One too, so dunno if its superior ability to trap dirt has any effect on the outcome. |

There was a test done on I believe "Bob the Oil Guy" website. It proved that paper filters are best for filtration, though they do restrict air flow a bit more than oil filters similar to the K&N one.
I tend to agree with the findings. I do not see a problem with replacing the air filter every 20k miles as I know they do they job.
So if you guys are happy with K&N, good on you, I stick to paper one. For no particular reason....;) |

| 20 bucks every 20k miles is pretty cheep for peace of mind... the guys in the shop highly disregard k&n filters. they have told me stories about pooched maf sensors and rediculously dirty throttle bodies(which i have seen myself on a mo with a k&n) another, don't by cheep fram etc paper filters. nissan maf sensors are quite picky and they tend to get wrecked much faster when a cheep filter is installed. i've replaced at least 5 maf sensors in the last month and 3 of them were because of cheep filters. |

| nl; I'm glad to get an inside scoope on this matter. I'll have to re-think the aftermarket filters......:) |

In my experience, the most useful part of the K&N filter is the sticker that you can put on the top of your air filter cover. Since I put the sticker on the cover, the guys that change the oil don’t bother to check the air filter. They don’t pull the clean air filters and bring them into the waiting room to show me that they need replacing because they just got filthy from handling by greasy, grungy hands.
:D :D :D |

Based on a friend’s recommendation, I put a K&N filter in my ’03 in September 2003. After a few months of use, I replaced it with a new Nissan filter because I thought it might be the cause of a repeating problem that began to occur. The Murano would go into limp mode at the first stop after driving non-stop for more than 100 miles. No codes were ever registered. The problem continued but went away after I installed a new battery in mid-December 2004.
I put the K&N filter in a big baggie and stored it in the garage. I doubt I will buy the kit to clean and re-oil it because I am pleased with the Nissan filters. I check the air filter every 6 months and replace when it looks dirty.

Here is a link to an old thread where the K&N Filter was discussed in April 2005. Has another picture of the sticker on my Murano's air filter cover.
Hey Dennis,
I had some similar performance - but it turned out that I needed to get Mo's injectors "relearned"....might be something completely different then what you had. I haven't had a spot of trouble w/ my filter.... |

Hi, NJ Joe. Maybe a k@N is like fine wine in this regard?:2: :confused:
Maybe you are right that a clean k@n is more porous? In the 1970's while I lived in Yuma AZ performance minded folks went to K@N due to the sand issues in desert, after doing mods to intake systems. Darrell. |
