This came out of a 2021 Kona 1.6L Turbo. 35,000 miles. Manual says to change at 40,000. They don’t look bad to me. Opinions?
Notice a difference afterwards?Mazda recommends the same for our 2.5 Turbo. I didn't realize this and didn't get around to it until 73,000. It was running well though and plugs all looked similar to yours. I changed them of course but took comfort at how they performed well beyond the mfg interval.
I would say slightly improved idle, but otherwise runs great as it did before.Notice a difference afterwards?
Look perfect to me...Looks like it should be a half step hotter even though plugs aren't made in 1/2 steps I assume.
I had an Elantra Sport with the 201HP 1.6. I changed mine at 42K and they looked a little better. I kept them in my tool box despite getting rid of the car. I remember the plugs being NGK but having a spark plug number only available from Hyundai dealers at the time, that probably changed by now.
I bought the car used with 20K on it, but assume this is the original NGK SILZKR8E8G spark plug installed in the factory.

My Honda has 40k service on it iridium's that I thought could go longer until they started missing. Not the same engine or hp but just change them. Hyundai has there reasons, what who knows but like you said an easy serviceThese plugs are stupid-easy. Takes about 3 minutes from start to finish to remove. But I'm not pulling all four until the change time. I was just curious as to why a short interval on what I thought were serviceable plugs.
