I think it's like arguing about whether the first oil change should be done at 2k or 4k or whatever miles because they "feel" that metal filings may be present as the engine set is or if they say 6k I'm going to go for 2k. Just waster money IMHO of course
Yep, I use that, the 5L is just a little harder to pour than the 1L one. Also FCP Euro is great as they don't ship UPS etc. which is for me prohibitive.
so i have a question. The OEM spark plugs are double platinum Bosch that Bosch claims are engineered to have up to 3x service life. 40k miles seems like a pretty "safe"/early time to replace them, but ok, that's fine. What i don't get is why people feel it necessary to change them at 4 years if you don't put anywhere near the 40k miles? Is it really a case of them just potentially being seized/too hard to get out? If you've only driven the car 20k miles in 4 years, what are you risking to hold off another year or 2?
This is a technical question, I'm genuinely curious the effect of age vs mileage (so yeah yeah do it just to preserve warranty, dont take a risk not withstanding)
Because that is what is required to keep your warranty and properly maintain your car.

warranty is 4 years. so if you don't do it at 4 years, it doesn't matter. And like i said, i'm looking for the technical reason, warranty notwithstanding. Properly maintaining your car - why? what happens if you wait 6 years? I know what happens if you don't change oil frequently enough, or brake fluid for 5 years... but plugs that are designed to last 30k, 40k+ miles... what happens if you that doesn't happen for 6 years?

lol you asking me? Maybe you should write a letter to Porsche and ask them how they concluded that was what was called for.
My mindset is more along the lines of "How do I take good care of my stuff" and do my best to listen to the words of the people that made the thing. Thinking "How much abuse can I get away with" is kind of strange.
You can google all the bad things that can happen from plugs falling apart, seizing, etc . Personally I change my plugs more frequently because they tell you a lot about the health of the engine / cylinders.

Apparently the seized argument has been made by Porsche going back to the 991 (I'm not sure about the 997). Because it's already a pain in the a** to access the spark plugs, having them seize would be that much more complicated.

i'm asking people on a car forum. I like to understand how things work so when something happens, i understand why. And not just "because i didn't follow recommendations" ...if you can't answer, that's fine. But the way I operate is more along the lines of, I want to understand why, if a part is designed to last 3x normal service life, and platinum plugs on cars are known to last 100k miles and 10 years, what makes this use case unique?

yeah, that's pretty much the only reason I've ever heard, and if that's the reason, that's the reason.

It's my understanding that platinum plugs don't do well in turbocharged engines, like the 9A2 Evo which is twin turbo. It would be surprising to me if that was recommended for use in these motors. The only options I have ever had / used on my turbo cars are iridium and copper.

Just to point out your original question was that you didn't understand why people felt they needed to change the plugs at 4 years. That is what I was answering, then it became about why that is necessary, which I did not sign up for.

it's the right plug they just don't have their lookup tool updated for 2022+
I'll take your word for it, and color me surprised. I guess they solved that problem with the platinum flaking off the electrode. Thanks for pointing that out.
