I used Bosch iridium spark plugs in my 2018, no issues
I've had my Bosch platinum spark plugs in for 120k+ kilometers and they still run as good as they did the day I installed them, back in 2011.
the original spark plugs died (delphi) so i changed them for Bosch ones
We used to put Bosch W7DTC spark plugs in them. No gapping required, smoother idle, and they last 60k miles, maybe more.
You can get NGK or Bosch plugs on rockauto for around $10. Not sure which was OEM, some like NGK for Mercedes in general but Bosch tends to be the OEM maker of plugs for MB.
They're both fine brands, I doubt you'll notice a difference. NGK is most likely OEM for your Civic, but it's not like Bosch is bad, they're OEM in my BMW.
The Neuspeed chips don't perform well at all, and the 2.0's do best with BOSCH FR8DS's.
Champion is OEM and what we suggest at work, but NGK has never failed us with any application. Bosch is generally terrible and we only use them if it’s a very specific application.
Although I prefer Bosch sensors over other brands in certain parts of my Mk 5 2.5, I will not buy Bosch spark plugs. Many professional mechanics over the last 3 decades have told me horror stories about them.
Warning about Bosch spark plugs!!! The piece of ceramic around the electrode failed. These were in a 2018 sonata turbo for about 10k miles. Thank God it didn't fall in...
