Yes, they did. If I remember correctly the Amsoil sponsor from TOB said they were doing them in small batches. These of course get sold out quick and we have to wait for them to make more.
I have seen the chrome filter on an S4R. I have to say I liked the way it looked. It blends in better with the gray/silver color of the engine. Also, it does not stick out very far. you only see about 1/2 an inch of chrome. Unless you have your engine painted black, I would just get the chome one.
Amsoils Ea oil filters are supposed to be better. The following is from their web site.
http://www.amsoil.com/"Absolute Efficiency
AMSOIL Ea Oil Filters have the best efficiency rating in the industry. EaO Filters provide a filtering efficiency in accordance with industry standard ISO 4548-12 of 98.7 percent at 15 microns, while competitive filters containing conventional cellulose medias range from 40 to 80 percent efficiency."
I read somewhere, (I think on the oil thread of TOB) that someone did an oil analisys after using the filter and the oil was cleaner than when it went into the engine!
If this is true, then it is better than any other filter on the market.
