The idea is to have good filtering and ample flow. General mass produced
oil filters do an average job on most cars, in my case I have researched
oil filters extensively and have found this filter to filter small enough particles 8 - 10 microns and give plenty of flow,

Most race filters like Wix 51515R or R series filters are around 60 micron filtering, this is because race orientated engines require flow more than filtering. I chose the Canton for it is expensive and had the flow and fine filtering attributes, according to their claims!
Another good filter is the Moroso race filters they go down to 28 microns and give plenty of flow for high performance engines, I wasnt concerned about going lower than 28 - 30 microns, all I wanted was better filtering than the purpose built race filters that other manufacturers supply. The Canton is a bit bling looking for this chap but really compact and as my car is dry sump I want plenty of flow!
