I would like to know has anyone tried this product it is called the oil filter magnet from WWWfilter magnet .com Cummins part # RA 365 it is listed up to 2003 model year but the 04-05 are the same filter so it would work It is a magnetic band that goes around the oil filter and catches the metal particles down to. 5 microns. I read the article from the web site and they tested it on a MACK and when they opened up the oil filter It was to my amazement to see how many metal particles this magnet had caught and they are also are claiming that this product will cause 70% less wear to the motor the price for this product$119. 95 without SH if any one is interested in ordering this product on the phone the #1800-345-8376 I spoke to a mechanic about this and he stated it a good idea and that it makes sense. if anyone is using a similar product I would like to hear your opinion about it Matt 2004. 5 Silver duallyQC 4X4 laramie Oo.
