I have to agree with you about the added piece of mind when you use a quality product. That is why we buy Beemers in the first place. Is it not?
You know as I sit here and write this, I have 4 oil filters on my desk. Just holding them you can tell, you get what you pay for. You would be amazed if you could feel the differences between them. Maybe I will cut into some of them to see what you get for your money. Personally, I feel a filter and oil change is cheap insurance for your bike's health. It does not cost very much and can't hurt the bike if done correctly.
There are only about 150 (so I hear) BMW motorcycle dealers in the US. Obviously not everyone can take their bike to a dealer for service. Because of this, I thought it would be fun to research who uses what filter and why. My goal is not to determine who makes the best filter. That is up to each bike owner. I just want to see if there is any sort of pattern or brand preference.
