Fram Suredrain oil drain plug
 

I was looking at the quick drain kit from CSC. It looks like the Fram suredrain (I think that was the name) I had used in the past. Any idea if it's the same... what size would it have been (or is)?

I know there are other quick drain oil plugs, but I like how small the Fram one was... less to get snagged or damaged.

I don't know if that's the same unit but the 2016 RX3 uses a 16mmx1.5 pitch bolt. The 2015 uses a 14mmx1.5 pitch. I have the CSC kit and other than cutting the hose down a bit it's perfect! I quickly looked at the SDx models of the SureDrain and I didn't see one that had the correct sized "bolt".
