I had a few quick questions that I was hoping you could help me with. My genesis currently has 57k miles and is coming up to the 60k mark. Reviewing the owners manual it looks like I need to replace the spark plugs, air cleaner filter, fuel tank air filter, and automatic transmission fluid.
Would you recommend performing all of those stated above? I have noticed on certain days I've been getting a lag in shifts, which I was reading could be a sign of replacing the spark plugs. Reading and viewing videos on YouTube it's no where near those who have had transmission problems, but would like to have butter shifts at all time...
Look forward to hearing your input as I know your cars go 200k and you know what you're doing!
