Rav4 P0300 code. Counterfeit spark plugs.

I had a P0300 code for random cylinders’ misfire for a couple weeks now. Today I went to check the spark plugs and all six plugs’ electrode had worn down badly. They were on the car for a little less than 40,000 miles. They are supposedly Denso Iridium in Toyota packaging from EBAY.

You can tell these are not even Iridium. The tip is usually very thin. You should never buy the spark plugs from Ebay because they are notorious for selling fake spark plugs.
The "Iridium tip" eroded away. Those stubs are the base. I would imagined real Iridium last much much longer.
