What's the spark plug interval on '05 911 (base)?

I thought that it was 40 K miles. That's what one dealer said but when I called another one he said it is 60 K. I recall seeing 40 K somewhere in the Porsche literature but he said that applies only to turbos.

(Of course when I talk about 40K I mean the milage not the cost of the service )

Check with your service booklet. I don't have it with me. If you need, I can post it later.

Thanks, I see it now: It's 60 K miles but no later than 4 years. I'm running in to time rather than the milage limitation.

I like of know is 60k. However, there is alway in my mind that I need to do that end of this year (4 year on my '06). Glad you find that.

Yikes I'm coming up on 4 years in a couple of months. I had been planning on 60K miles. Didn't realize there was a 4 year spec for replacement.

I don't know that I really buy into the 4 year requirement. Spark plugs don't wear out based on time. They wear out based on usage/mileage. Just like brake pads and clutch disks.

I think its Porsche's way of making sure they make their money no matter how little you drive....

boolala

....and that money they quoted me was $650. Does that sound right?

for spark plugs alone? i dont know where the 997 spark plugs are located but there's no way its 5.5-6 hours of labor...

boolala

I think that they charge $150 per hour of labor. Plus the costs of the plugs.

JW911

I think I will wait until 60K miles. 40K miles is ridiculous. Most vehicles these days specify 100K mile plug changes.

Early build '05 997s are 4-5 years in service. How many of you have changed the plugs?

Macster

could see the thread lube deteriorate and corrosion of the plug and plug hole threads start up. Then upon plug change the threads could be damaged in the head.

On a related note, if you plan on keeping car a long time you might consider having the exhaust manifold gaskets at the exhaust manifold/head interface replaced. Even if gaskets do not need it and they probably don't, this gets the exhaust bolts removed and replaced with new bolts, new thread lube and of course new gaskets.

Then later when car out of warranty and you might be faced with some exhaust work -- like replace a converter (like I'm facing with my car) -- you have a better chance of getting the exhaust bolts out without damaging the threaded holes in the heads. These holes can be fitted with thread inserts but easier to have mech. do it while car on lift at shop with all the tools vs maybe doing it in your driveway or garage.

Sincerely,

Macster.

1-2 hours. I can't imagine an experience mechanic taking more than an hour.
Then, again Porsche charges $700-800 for the two year service that requires an oil/filter, air filter, and making sure that all the other fluids are okay.
Gentlemen, its time you talk to your father and start getting your little hands dirty...unless you really don't care about how things work and don't mind dishing out big money.
