I contacted K&N regarding their HP line of filters to get some more info after watching the Engine Masters oil filter shootout episode. The show stated a 10bmicron rating, and descriptions on Scummit's website also states that, but I wanted to get actual data from the source.
I sent a couple emails to the tech support, and they couldn't even answer those questions. They just say they're built to meet or exceed oem specs. I wouldn't consider using their products if even they don't know what's in it.
