I searched forum for K & N air filter replacement. Most posts indicate that there is at least some improvements in car response with it. Well, while it's still questionable I am willing to give it a try and "risk" my fifty bucks for it. :rolleyes:
The question that I have is regarding the sound of intake. Is the sound any louder with K & N filter? Or there is no noticeable difference in noise compare to stock one? I am talking about drop-in filter, not the intake replacement. I am very sensitive to engine/road noise and would not want it to be any louder then it is right now with stock filter... |

| Louder at mid to high rpms when you mash on the gas pedal. Negligible at low rpms and at normal cruising speed (we'll hear some road noise or nothing much really). |

just dropped a replacement K&N air filter into the airbox recently...
did not notice any differences in noise levels as compared to OEM..not even at higher rpms..but then again...at higher rpms, i am driving on the road...tire noise, music, wife chattering..etc..
I thought it was the K&N air filter that had decreased my average mpg. I was getting 17.1 (90%/10% city/highway) to 15.6.
nope. just had a heavy foot...getting 19.0 mpg. |

| I did not hear a noise difference. MPG gains are minimal, if at all. The main factor for me in buying the K&N air filter is that it never needs replacing. When it gets dirty you can just clean it. This will save a small amount of money in the long run. |

After reading this I went back to a honda paper filter. I had tried the true flow for 6 months because it was better built than the K&N, but felt it might not be getting all the particles even though it wasn't in the test. |

That's why I now use the True Flow. Baja runs, etc. use foam filters, there is a reason. They have a higher capacity for trapping particles than paper or oiled gauze. A paper filter would clog up very fast, but that's not the same as saying it does not filter well. The test done by True Flow is quite impressive, even if it might be biased.
The other racing types he tested are not even available for the MDX. I have heard the ITG is a very good one, but expensive and limited applications also.
I had an Amsoil before, some years ago. The build quality was lousy. |

Ok, so I learned that the performance increase with K&N is microscopic, or even less then that and on the other hand I somewhat compromise filtration... Ok...
Dale, what's True Flow, why do you use it and where do I get it? Also, do you feel difference in performance with True Flow or is it purely utility issue for you? Thank you. :cool: |

Go check out there website and learn about them. To me it seems to be a better solution. Much thicker media to capture a greater volume of particulate matter, but due to the large cellular structure, air flow is not impeded.
Paper is not a bad way to go. It is just self-limiting by it's nature. As it fills with dirt less and less air gets through. The greater surface area of other types allows air to continue to flow with greater ease.
While I have heard other negative things about K&N over the years, I have never read anything very convincing.
They are still used by many engine tuners for some very expensive machinery. I have never seen statistics to show engines wear out faster with K&N filters, etc. I am sure it would have to be a very long study and many factors such as environmental would need to be considered.
I think for most of the suburban and open road driving most of us do, the differences in filters is a moot point. Sorry I can not offer anything more concrete than that.

Dale, you have been more then helpful, thank you.
I guess I can't do much harm by sticking with stock filter, but I am on the quest for "improvements". This is my first luxury car (RX300 does not count - its' wife's) and I am still excited about it and feel like "making it a little better", especially if it does not cost much. You understand I'm sure...

I just took out the factory filter. MUCH more power- you can REALLY feel it.
I am not too concerned since it is a lease....
PS CTPYHA... you still don't own a "luxury" vehicle.... |

What filter did you go with? K&N?

Just took the factory out and didn't put anything back- I want the engine to BREATHE man- none of that girly-man filter business for ME.
A
PS Joking. It is stupid to think that you can affect any meaningful performance by chaning the filter- unless you drastically reduce the filter efficiency to allow damaging particulates in. But this is what the K&N oiled filter does and folks line up with their $$... sounds different, must be faster... |

hey guys:
need, "More Power"
More Power in cars and computers and camera are about the only things that we could converse about. my Japanese brother and law.
we are driving around in his Toyota low budget Lexus. it has a 4 banger in it. something like a 2.2 liter engine. what a POS. well it looked just like a lexas, but had no balls what-so-ever.
Ok back to my question.
has anyone ever put a stick in an MDX? which car did this engine come from, that could have had a stick, and that would be half the battle.
if yes, how hard is it.
i would like to keep my MDX, after the transmission being replaced, but I can't rely on this tranny long term.
cheers,

I needed more power, so I bought an M5.
If i needed more power in the MDX I'd buy a Cayanne ...
The MDX is an awd vehicle... there is a *bit* more to it than figuring out where a clutch pedal might go! |

It is serviced the same as the K&N as well as others.
Quite simple.
