This year's street bike oil change nearly defeated me. The nut rounded off instantly, and using my go-to oil filter wrench (the Vise-Grip style) required me to essentially crush the can before I could apply enough torque to remove the thing. I was seriously concerned that it'd just rip right off, leaving the base still on the engine. In other words, the metal is so crappy that it won't stand up to even minor force.

Went to the local dealers and discovered that OEM is in fact comparably priced. I'm done. OEM forever.

I second sticking with OEM. On another note, most racing orgs have banned anything but OEM, due to failures. K&N has blown up on track a few times last season.
