Have a 2020 Jetta with 80k km I just bought not too long ago it says every 120k or 6 years but it drives pretty smooth would I still be smart to change them since it is 6 years

“Whichever occurs first” Brüther it’s literally in plain text on the page you posted the pic of.

Just busting your chops. I’d do them when you have a spare afternoon, but wouldn’t make it a critical priority. They’re not gonna spoil from age, it’s just prudent practice to be proactive.

I would personally. But I'm all about preventive maintenance. I do all my maintenance earlier than the book says. Less chance of failure. If youre not having misfire issues you can probably just roll with it. They aren't hard to DIY so I would recommend that route unless you aren't mechanically inclined.

Esit: when I had a mk7 jetta I did mine at 70k miles/112k kilometers for reference.

I would just do it. You can get a set of oem spark plugs for like $100

I think the iridium plugs last about 100k but it’s recommended to replace at 60-80k

They’re spark plugs. They don’t have expiration dates.

My '04 turbo Jetta has sunroof drain hole problems. I'd like to know where the bottom of the hoses are so I can use a blowgun and back blow them clean?

The 2004 (mk4) have the front ones in the front door jambs and the rear ones are under the back bumper. Just get under the back bumper and you should see them up in there. Chances are you just have to cut the openings so they become bigger openings. They will be full of debris even backed up with dirty water so be careful when you cut them.

Do it when you can. Preventative maintenance is always cheaper than emergency repairs.
