I put Autolite Iridium plugs in my '06 N52 20k miles ago because of a crazy sale/rebate. It runs as smooth as a new one.
Pros: runs smooth as new

You're on the right track- replace those worn out plugs. Pre-detonation started on my '18 at 30k. Increasing octane rating to 93 worked up to 58k miles. $50 for a new set of [Autolite Iridium XP5363](https://www.amazon.com/dp/B078KWTCF2?ref=ppx_pop_mob_ap_share) resolved this problem.
Pros: resolved pre-detonation problem
Vehicle:
Ford
Mileage: 30000 km
Part number: XP5363
Normally that's a result of a failed spark plug seal. If you have no other problems I would put new spark plugs in it and check them at the next oil change.

Autolites gotta be the worst fkn plugs on the market rn.

autolites are some of the worst spark plugs, grab some NGK iridium’s and it should be fine
Cons: worst spark plugs
I have a 2019 GTI with 65k km. I decided to do plugs and when I saw how expensive OEM were, I said screw that, i'm going to try the iridium auto value basic ones. I thought the difference in quality would be negligible. I ran the Autolite XP5325 plugs without gapping. All seemed fine but then when pulling on to highway under load at 3k + RPM, misfiring like crazy.
Cons: misfiring under load
Vehicle:
Volkswagen
Mileage: 65000 km
