Car-spotting thread

Ok, so on the one hand I can understand this, the plugs and head are made from different metals with different thermal expansion coefficients, and over the course of seasonal changes and driving maybe some corrosion can form between the metal threads of the plug and aluminum heads that could cause seizing (this is a very German way of overthinking). On the other hand, I've changed plugs in aluminum heads that were way, way over 4 years with zero issues. Its called using a torque wrench correctly when you put them in.

Changing the plugs on a Cayman isn't exactly an easy DIY either, its a PITA. You have to take the wheels of the car, navigate around the exhaust plumbing to reach the plugs which are super recessed in the head. There's a lot of cursing and contortion. If you have a turbocharged 911, you also have to take the rear bumper off, then move the radiators to reach the plugs. Lots of $$$$ and coffee at the dealer.

I mean, it's espresso at the dealer but everything else is accurate.

Robot, this is Porsche not Bugatti. However, its been rigorously laboratory tested to repeatedly deliver a very specific quantity of coffee at a specific concentration within a temperature range of + or - 1 degree, and it probably holds the Nurburgring lap record for coffee machines. And you'd better believe its all built into the cost of your service.
