Before FRAM and many other companies went OFFSHORE (China) for manufacturing their filters, they were made in America. While here, the companies DID manage to keep their quality in check. BUT as we have said, there IS a reason a "FRAM" or other brand name filter is sitting on a Wal Mart shelf for $4.98. Common sense screams out the answer.
You will never EVER go wrong with a Suzuki OEM FILTER. NEVER. I have used them and I like them, but not so much the price. But hey you get what you pay for in most instances. NAPA and WIX are easy finds as well. K&N is an easy find, at least for me, Autozone carried them.
As for the use of an oil filter, there is NO way anybody can successfully 'argue' the absence of an oil filter is GOOD for an engine. It simply is not. The MOMENT you start using the oil for lubrication, when the engine is cold, the blowby gases and extra fuel will contaminate the oil. This is about as simple as I can get it: "engine combustion and pollutants from the atmosphere and from various other sources such as engine additives produce soot, dust and mineral particles that can abrade and damage engine parts. If these particles are not removed, the engine will eventually fail. Removing abrasive particles from motor oil is the purpose of an oil filter."
Early automobile engines did not use oil filters. For this reason, along with the generally low quality of oil available, very frequent oil changes were required. The forerunner to oil filtration was mesh and screen strainers. Same with VW Beetles...they require FREQUENT oil changes if you have not modded your bug to accept an oil filter.

Good luck and by all means use what you like, and have had success with. Others and myself are only pointing out what we have seen and experienced. But if you tear apart the filters you will see a difference in workmanship. Crushed media, strings, cardboard end caps, inferior anti drain back valves, poor construction. I personally would rather run an empty can than a F**M. I switched in 1990 when I saw the light and have never looked back.
Quality filters are not expensive, they just have to be found.
Cheers to all.
