I like the bkr6ek they are good plugs. I have noticed that with eqp the car runs a bit rough after a while.

I tried them both one after the other.
I didn't really notice much difference, compression still fine, detonation was still up... I just found the IX's a bit smoother at idle, so I went with those.
