Fake Denso FXE20HR11 Spark Plugs?

Or something else?

At 100k miles I had my son's 2011 Versa Hatchback's plugs changed out. 20k later he's getting an occasional Service Engine Soon (P0301) indication. Had a local trusted mechanic do it for me last time but this time I figured I'd tackle this myself. Between the many posts I've read here and the YouTube vids... I was ready.

First thing I noticed was how much the electrode was worn out on all 4 plugs. Never seen so much wear in such a short amount of time. Those plugs were replaced in May of 2018, 20k miles ago.

I will admit my mechanic only changed out the plugs. Not his fault. That's what I asked him to do. Coil packs were reused as were the intake manifold and throttle body gaskets. I know better now regarding the gaskets.

This time I replaced everything. New Denso coil packs, the same plugs (bought quantity 8 last year from an eBay seller with excellent feedback) and new gaskets. I even cleaned the crude off the intake manifold and the throttle body (using 90% alcohol).

Put everything back together and the car runs fine. Have yet to take it for a test drive.

After doing this job I'll admit it wasn't as bad as I thought it would be. Sure it's a PITA to have to remove so much crap to get at the plugs, but now that I've done it I won't feel so intimidated next time. And if I ever need to get to an injector, they're right there.

So, as for the previous occasional P0301 issue... thoughts?
