ekpolk,
Is this a "clicker" one or not. Not sure exactly what I am looking at here.

Definitely NOT a clicker. I was able to push it open a little with a little pressure, midway with medium pressure, and all the way with full pressure.
Well clearly Bosch Premium filters vary by model. Looking inside mine, I saw a somewhat large, robust looking spring. This spring would take the place of that stamped piece of sheet metal in that picture. If you have a preference (surely BITOGers do) then just open the box and look inside the filter!quote:

Interesting. I guess it's size-by-size with the BPs. Below is a picture of the guts of the Bosch Premium that fits the Nissan/Infiniti VQ35 V-6 (which powers my G35). Unfortunately, I didn't try to get a pic of the other side of the valve, but it is a progressive, spring-loaded mechanism. I know, I've got my pinky stuck in it. . .quote:

Ekpolk...I'm looking at the other new Bosch Premium #3500 that I bought at AutoZone when I was there last,the other one used for a week then removed and dismantled.It's the big Ford oversize that I am using on my Jeep's 4.0L engine (still using the Ford oversize just not Bosch Premiums).On the box it says it has the syn/cellulose "filtech" media.Sorry when I look inside I can see that cockamayme "clicker"Too bad they looked great inside except for the two pieces of sheet metal pressed together with holes in one of them,that is the bypass valve
I guess the morale is that we can generalize by brand, but we need to look at filters on a model by model basis.
There's a substantial difference between the basic Bosch and the "Bosch Premium." I have not cut up your size Bosch Premium, but I have cut up the one that fits the Nissan/Infiniti VQ35DE 3.5L V-6, and its bypass is definitely NOT a clicker type. Are you postive that wasn't a "regular" Bosch? I'm not interested in getting into one of those "I'm right and your not" exchanges, but I do occasionally recommend these to friends, and if some Premiums have a clicker, that would give me something to think about.quote:

There's a robust spring inside the disassembled filter shown in my picture too. It's on the other side of the little black "dot" (which is the actual bypass valve) which you can see on top of the filter element in my picture. Unfortunately, the remnants of that filter are in my BOQ room in New Orleans, and I'm home in Pensacola until Wednesday, so I can't supplement the pic until then. The sheet metal part you're looking at keeps the entire element pushed down on the base plate. When you autopsy this filter, you find it between the top of the can and the element.
Pictures of the clicker type bypass valve:
Here's a picture of a Bosch with a clicker bypass valve.
versus one with a coil spring and plug design:
There is another design that has the bypass valve at the baseplate end of the filter. I'll leave it to someone else to find pictures of this design.

The filtering media is different. I noticed the same thing you did when I cut a bunch of filters open, but I went a step further and found info that proved they were different.
I really need to update my page...

427Z06, thanks for the pics, now I see.
Aren't the clicker bypass valve a recent development? Their might be old stock of the slow moving filter models that still have the old valve.

I don't know about Bosch, but Purolator Pure Ones can handle long OCIs. One of the best filters on the market.
I'm trying a Bosch Premium for the first time right now on my '90 Voygager oil-burning smoker of doom.
I tend to change the oil fairly often on that one (or at least dump in more Pennzoil 5w30), since it burns a lot anyway, so I'm not worried about long intervals.
