The fram was what I expected from cutting open other frams. Took about 2 minutes (scissors and hand power) to get the thing apart enough to measure how much material is in it.

Comparing it to this data:
http://www.overboost.com/story.asp?id=1143
This FRAM had the same number of pleats. However, instead of the media being 93.5 square inches, my filter was 101.25 square inches. Still an awefully low amount of filter media compared to other filters, nonetheless. The pleats on the filter were not straight and didn't look confidence inspiring. The element was also noticably weaker and more easily torn than the ST's.

What really impressed me as the ST build quality. Mostly even pleats, no sideways and crimped looking pleats and strong glue. It took 10 minutes of using knifes to get it apart, because the scissors and my hand power was not enough to do anything to the element. Total area for this filter was 119.25 square inches.

The part of FRAM's glue sticking better is total crap. Ripping fram's glue apart (at room temperature) was easy. Even after 20 minutes of fiddling, I can't get enough torque to remove the filter from the glue/filter assembly. This material is also much stronger than the FRAM's filtering material.

Personally, I have no problem using this filter whatsoever. It will become my filter of choice unless I race the car or I decide I want to stop buying from Wal-Mart.


Oh yeah, and it looks like the Orange Wall of Doom is shrinking and ST is growing. Last time I went there the stock of ST's were half gone. This time they were fully restocked!

The first link showed a STP filter with a telltale ADBV used in the Wix filters I have checked, rather than Champion like some others. Looks like another example of how it is a good idea to check various makers of whatever filter for your particular application.

When doing pictures, overboost had a tendancy to get some things wrong. Look at the purolator premium plus. It's just another pure one picture. but yes, that's another reason why I wanted to cut open the filters for my car. the other filters I have are Advance Auto AA3593a, STP 2808 (I want to get a 2903 and cut that open too), Purolator 14459 and 24458, AC Delco 1127 and another ST3593a (which I'm not going to cut until after I run it). Probably the only two filters I see myself cutton open are the two STP's and the smaller of the purolator. I'm probably going to be sticking with the Purolator 24458 because that filter at a glace seems to have the most filtering media. Then again, I may cut one of those open too.

i can save you the effort of the 14459. just imagine a typical purolator that is clock full of filter area.
there is no big can small filter syndrome with the pl14459.

that stp does indeed have a wix adbv, my stp had one as well. i wonder whats going on with stp? seems like a multitude of manufactuer parts are in there things.
 
Maybe they are just doing what everyone else is doing these days,contract out the componants to sub-contractors, and then just ASSEMBLE them in whatever location costs the least per sq foot..
 
True, but I still don't completely trust overboost. They've messed up before in the past. I will be cutting open a slightly different STP (the one for my car) and Advance AA3593a today.
