Since we're suppose to change our air filter on the Cat C-7 engines installed in the Freightliner XC chassis every 3 years, what brand, part number, price and source are most of you using? Do different brands of filters have better elements and hold up better than others? Is this one of those situations where you get what you pay for? Did a search on the Forum for air filters buy didn't find that much information.
Both of my Journeys (2000, and 2005) came to me with the FAR 114880 003 installed. Although I bought the MH's used I don't think they had been changed.
Like oil, I think it is more important that they be changed regularly than to worry about the brand. If all of these filters were sitting in front of me I couldn't tell the difference. From the box and plastic inner bag they came in to the thin coat of black paint, etc...
It's my opinion they were all manufactured in the same place.
