Did the 40k service plugs seem to be in good condition but were almost seized. The threads were dry.

 

Air filters after 38k were dirty as expected.

 

Were the plugs particularly difficult to change? Is this a DIY project for someone with moderate wrenching experience?

 

So said my mechanic.

 

Actually, I'm glad to see the filters look pretty good for 40K.

Wow!
Almost 40k miles? Thats a lot of driving.

 

Congrats on the mileage, this car is meant to be driven.
Doesn't Porsche replace the air filter a first time at 20,000 miles? (got mines replaced a few weeks ago).

 

Cabin filters at 20k. Engine filters at 40k.


I'm going to replace them at 20k intervals from now as the rear valence seems not too difficult to remove They were dirty as I could not see light passing through

 

What I am doing too (in fact did it already after 10kmiles to check).

 

I "mistakenly" changed my engine filter at 20k miles. They were quite dirty (but I live in NYC).

RNL -- how much did you pay for the spark plug service?

 

$550 plus the parts I provided


Reset service meter
Check belt
Spark plug
Filter change

 

Thanks

 

Did you find a degradation of MPG at the end due to the dirty filter?

ChuckJ

 

Probably. I did see a 1.5 to 2 mpg improvement after they were changed

 

Good to know.
