ck55, will do.
FYI, I just received an email reply from this gentleman who runs this website and did this excellent, indept review of some of the filters out there,
http://www.ntpog.org/reviews/filters/filters.shtml
In the email, I asked him what he thought about K&N Gold oil filters (which I'm currently using, #HP1004) because I couldn't find any of the highly recommended filters in his review around this neck of the woods. He said that the K&N Gold filters are "Excellent filters. Basically the same as a Mobil 1, but I believe they use a better media. It happens to be made by Champion Labs (who makes Mobil 1, STP, and Bosch)." (You getting this, N_Jay?)
And then I referred him to this link
http://www.acuramdx.org/forums/showthread.php?s=&threadid=10497 and expressed my wish to use the M1-105 filter on my Pilot and he replied with this, "I use the M1-105 on all my Hondas and my Isuzu Trooper which uses the Honda size. It works well. I can't say that it improves on anything, but I feel a little better about having it on there!"
But I did ask him if the different pressure requirements for the Pilot and the MDX is something I should worry about and he said, "Considering they are basically the same engine. I seriously doubt they use different pressure springs. I further can tell you that if Honda/Acura hands you the same OEM filter for both vehicles, guess what-they are the same pressure. Do you know if they supply different ones, OEM? This is normally something to worry about, but I don't think so in this case. I have verified with Mobil 1 that the bypass spring in the M1-104 and M1-105 is the same pressure (I forget exactly what psi)."
ck55, is that the answer you're looking for?
Now, I have to find out:
1. If the recommended filter by Mobil1 for the Pilot is indeed M1-104, then I think it's safe to use the M1-105.
2. I do know that according to the link over at the X site, the book lookup filter for the 01-02 X is M1-104, therefore....
3. to be further sure, find out if the Pilot and the 01-02 OEM filters are basically the same ones (that's why I'm asking Tim, hope he doesn't mind).
I tried calling Mobil1's filter tech support line, to get the facts right from the source, especially about the bypass spring and the pressure numbers, but the toll free number's not available in Canada! Arrrrgh!!! So, if either 1. or 3. is true, then I think it can be deemed that M1-105 is good on our Pilots as well. Hope that makes sense.
