However, I have been able to discern that it's made on the same line as the K&N filter, but will a media that is slightly better at filtration. Based on testing by others I still think this is a really good filter. On the other hand, it's big brother the SDF-44 did not filter oil well at 13,000 miles. Proving that an oversized filter is not always a good thing when it comes to filtration. The K&N HP-1004 is a great filter. The internal honda accord oil filter construction is the same as the Mobil 1 filter, but it does not filter the down to as small a particle size.
The FRAM x2 (and only the FRAM x2 Series) is probably the most heavily constructed filter I've seen so far. Though all of the Japanese made filters were of exceptional quality, the Fram x2 was as good in every way. Of note with the construction were the following features: metal screen backing the media, heavy metal end caps (fram oil filter for toro tractor have cardboard), and 2 layer filter medium. As with all of the Fram filters and OEM Honda oil filters the x2 uses the standard spring loaded plastic by-pass valve that many people do not like. However, lab tests do not indicate that the valve jams or fails to work. It's possible that a hard enough impact at a sharp angle while the fram oil filters chart was by-passing might cause it to jam open, but I suspect the fluid within the filter would prevent this. While both the STP and the Bosch filters were at one point good filters, they are now manufactured off shore of sub-standard parts. There was also a complete lack of a well functioning by-pass valve. With most filters there is an obvious and discrete by-pass valve, but with these filters the can spring and the by-pass valve are the same. The real issue is that in order for the filter to properly by-pass the entire automotive oil filter wholesale assembly would have to move down during use. That is actually not possible with filter assembly properly seating into the anti-drain back valve. This means that the by-pass will effectively never work. In the center of the of picture below you see the filter assembly (top) and the can spring/by-pass valve (bottom). A serious word of caution to experimenters: if you are thinking of trying out different/oversized filters, or ones we haven't listed here, be careful. In the course of testing, we tried a Purolator PureOne oversized triphammer; it leaked pretty bad. Upon inspection, the gasket was found to be MUCH too large, large enough that the oversized M1-105 filter (and M1-104, OEM size) gasket actually fit inside it. If you experiment, be very careful, and look over the filter before testing it.
Also keep in mind the difference in bypass spring pressures as this may dramatically affect the way your vehicle's oiling system operates. Check with the fryer oil filter manufacturer for exact bypass spring specs, most will usually provide this information via simple email contact with you. Cutting oil filters open isn't as easy as it sounds. But when I finally got smart and pulled out the dremel tool with the cutting wheel, that did the trick.
What I did was cut the case just above the seam that is located by the base-plate (I'm calling the base-plate the end that screws onto the engine - it's the heaviest plate of the coupler). This analysis covers some basic key-measures of these oil filters.
Also, I am not an oil filter expert, I've just been maintaining my own cars probably like most of you and have been doing it since I started driving at 14, today I'm 50. I've put on and taken off a hell-of-a-lot of oil filters. I'm maintaining 5 cars right now (2 for me, wife's, daughter's, and son's). I don't know anymore about automotive oil filter cross reference, though, than you'll know after reading this report and others you might find on the internet.
I've found Toyotas to be most excellent automobiles, really durable and well made (but you know that already) and I've owned 4 of them with 3 of those being Corollas. I think Corolla is the highest value vehicle made today, just my opinion, its a great around town car that has the capability of making fairly pleasant interstate trips and it doesn't beat you up to bad in the process.
Over the years, I've bought about every oil filter brand out there.
I imagine there are engineers out there that spend an entire career designing oil filters. I know a whole lot more today than I did, so its been worth the effort. I can see there is a lot of science, both design, material and production, in oil filters.
