Well i've been busy this weekend so i'll catch up on a few things.
First..i'm certainly not disputing what lubeowner is finding when he cuts open filters.
Where I think he needs to think a little harder is what would cause a filter to look like it does after he cuts it open. He's found 1 filter where the pleat didn't seat properly in the end cap. Yet he's gone bang on about the clicker valves not working properly and laying the blame there.
There are those in here who want to talk about the laboratory testing versus real world. Well in order to design a new filter the lab may use cadcam but that is but part of the first step. There are "models" built and tested to "specs". But long before any new filter design is produced for the market ( be it new media or an E-core) there is lot's of "real world" testing. Champ had over a million miles of testing on the E-core before allowing it to go to market. It's the same thing they are doing right now with Mobil with the new extended life filter they will be selling soon. Why can't you buy the new Mobil filter? Because they haven't made up their minds which option Champ has designed to actualy sell to the public.
The testing is not done on brand new factory engines. It is done on real world cars. new and old. Cold weather and hot. Dusty conditions and mountainous.
Second..Private label accounts don't tell Champ what specs to build the filters to.
Champ has the engine manufacturers specs and they are the ones who know what "options" they can provide and manufacture for individual private label accounts.
Only with OEM engine business does Champ work with their engineers to provide a filter to their specs. Sometimes the spec is unrealistic for production and the OEM revise their "specs".
Third..profits. I'm glad everyone seems to think Champ is rolling in the dough because of making the E-core filter and it's "cheaper" than the standard metal endcap and by-pass valve design.
Nothing could be further from the truth. It is a more expensive filter to make. Just because retail pricing hasn't gone up, doesn't mean it is a cheaper filter.
This is why competitors at this point in time either aren't making their own metal free element or have delayed doing one themselves. They know the score when it comes to a complete new production line and design.
Fourth: I've said before I will answer questions about filters in general. I've "defended" other brands in previous threads. It's just that the E-core design is like politics in this forum at the moment..
Fifth: I happen to sell Mann, M.P.Filtri, and Mahle filters amoungts other brands. Including Champ, Fleetguard, and Donaldson. One of our biggest accounts is the largest dealer in Texas for Baldwin. As i've mentioned when I joined this forum Baldwin, Donaldson, and Fram at various times were my accounts when I worked for Champ. I've been through Wix and Frams engineeering departments and have a pretty good idea about their test equipment. I've been through some of Donaldsons lab but not all of it. ( I was only interested in a certain test that I wanted to discuss)
Sixth:..For the person who mentioned blame anything but the filter when it comes to complaints. I can only speak for what I know about Champ but they have and do pay warranties on filters returned where there is a defect. As I do think the other filter manufacturers do as well. I don't care what the marine outboard people do.
But if it ain't the filters fault..then it is the conditions the filter was subjected to.
And last..GM and their by-pass in the mounting head. Yes it does work effectively. But don't you think Ferrari, Jaguar, Mercedes Benz, Honda, Maserati, Porche, VW and the rest of the world wide OEM's might also know the effect of putting the by-pass as part of the filter design? I realize you're probably taking a shot a Ford or Chrysler but they ain't the only ones who put the by-pass in the filter element...
And btw..
I have seen Ferrari and Jaguar filters go down the Champ production line, they don't build them very often though to low a volume..
