Hi Folks,
2014 Lexus ES350, 81,050 miles
I bought a new Depstech DS500 borescope so I decided to have fun and look inside cylinder #4. No driveability issues, power drop or MPG drops at this time. Photos below. Should I consider any type of intake/injection cleaner at this time?
Thanks for your time!

That's pretty normal and it's running okay. I'd leave it alone
