Car owners are also able to add DIY maintenance items to their cars carfax. I would suggest that anyone doing their own maintenance do this.

Some might be, others seem to have no basis other than to keep the dealerships fat and happy (time based spark plug changes, so do they go bad like a loaf of bread?). People often say the Porsche engineers did something for a reason but that presumes the engineers are making these recommendations rather than the bean-counters.

Any evidence it isn't? These guys have not exactly shown themselves to be corporate paragons of virtue. Again, why do spark plugs need to be replaced at 4 years if there is only 10k miles on the engine (not uncommon for a 911)? If they sit in the dealer's stockroom for four years do they throw them away?

If I had to guess, it would be that they are trying to avoid galvanic corrosion. Steel and aluminum don't play nice given enough time.

Hmmm, that's plausible and worth considering. Probably depends largely on the operating environment. I'm in So Cal and have had no issues with going way beyond the four years on my last two 911's but you do read a thread every now and then of someone having one gall up when trying to pull it.

I just think back to 90s ford V8s pulling a chunk of head out and/or leaving half the plug in there when trying to pull them. :\

Well.... if our cars were in Europe the maintenance intervals are 2 years and 20,000 miles but here they are 1 year and 10,000 miles.

Must be the ocean crossing that makes the difference....

Maybe send a tweet to the NHTSA about FMVSS? I dunno.

I'm not an engineer. I just value having a nice maintenance log upon sale of the car over sticking it to "the man" by pretending I know the car better.

Besides, plugs are virtually free and easy to replace, so why wouldn't you?

This is a little off subject, but I'm asking anyway. My car will arrive November first, my understanding is that the first oil change is on Porsche. The second is brake flush plus oil, filter. It looks to me like the intake filters don't get changed out until the third service. I live in a fairly dirty environment compared to the city, and will want the air filters changed out at least annually. Any idea how much I should reasonably pay for that added service?

I tend to follow Porsche’s schedule but not to the letter. I don’t come close to 10k miles a year but change out the oil & filter every 5,000 miles or 12 months, whichever occurs first. I swap out the cabin air filter based on mileage on all my cars and that’s what I’ll do on the 911. Cabin filter change is as simple as it gets on any car. I plan on replacing the plugs and air filter (clean) at 30k miles or 4 years, whichever comes first. My car is tuned and probably runs hotter than your average 911 on my spirited drives, so I don’t want to deal with plug seizure issues. Brake flush is all dependent on how you drive your car and I personally use the “moisture level” method. I’ve done my share of brake flushes and from my experience, brake flushes are overkill. Just a FYI, some dealerships only change out the fluid in the master cylinder and claim to have done a brake flush. Take it for what it’s worth. I’m a DIYer when comes to my babies but our family and kid’s vehicles can get the puppy mill treatment by the stealership. As my dad always used say, DIY if you want it done right.

I do those things every year religiously even though I'm way under on mileage.

Cabin air filter change is as easy as it gets. Just YouTube or search this forum. It’ll cost you maybe $50 for the 2 filters. One is in the frunk (pre filter) and the other is under the glove compartment. You don’t need a special tool. Or, you can choose to have the dealership do it for much more. Me personally, I’d rather light those Benjamins for 10 seconds of heat in July in Death Valley.

how?

No one is trying to "stick it to the man", good grief (and that's from an engineer). I won't speak for others but I don't like throwing money away on unneeded items for some nebulous "peace of mind" that's never defined or explained. A little skepticism in life can go a long way. Did you read the recent thread from the relatively new poster asking if he got ripped off by paying $569 for a dealership oil change? I'm sure his "trusted Porsche service advisor" told him it was absolutely required. What a crock. Not to pick on the poster but the fact that he even had to ask is a pretty sad commentary on human gullibility. They charged him $9 for "parts cleaner" which was probably a few sheets of paper towels for crying out loud. I don't pretend to know better, I do know better. $500 dealer oil changes are ridiculous. $3500 dealer brake jobs (where they throw perfectly good rotors in the recycle bin) are absurd. $1000 spark plug changes (or whatever they charge now) after 10k miles are nonsense.

I might take the word of Porsche a little more seriously if their dealerships weren't thieves, VAG leadership didn't knowing engage in the emission scandal (which now looks like it extends to the 9A1 engine), they didn't try and cover up the IMS bearing fiasco, and they didn't ream you for $14k for a remanufactured PDK when a $50 part fails. Don't get me wrong, I love Porsche engineering which is why I'm now on my fourth 911. To think that lends credence in any way to the business side of things is laughable.

Edit: BTW, didn't mean for this comment to be too over the top as I know we all have different perspectives. Apologies if it came across as overly inflammatory.
