Spark plugs

[Frank Patrick]

Forgive me, I have searched and can not seem to find a simple DYI for SP removale. Read that tires must come off, anything else or is that all there is to it?

Hi,

You don't actually need to pull the Tires.

Raise Car securely.

Using a 6mm (?) Hex Bit (or Allen Wrench), remove the 2 screws holding the CoilPak to the Valve Cover. Twist slightly while extracting the CoilPak (if inexperienced, do one CoilPak at a time to avoid mixing them up).

Using a 5/8" Long Spark Plug Socket (or a normal one with extention), remove old Plug.

Install new Plug and torque it to 26 ft. lbs.

Re-insert CoilPak and push it til it clicks

Reattach screws to Coil Pak and torque to 6-7 ft.lbs.

It's also a good idea to run your finger in the hole to insure that there is no Oil on it indicating a leaky Spark Plug Tube 'O' ring - replace as necessary.

Also, stick with OEM Plugs, there is no advantage, but a possible disadvantage, to using Aftermarket Plugs. Hope this helps...

Happy Motoring!... Jim'99

After reading this I'm starting to second guess the point of having the dealer do my spark plugs as part of my 30K service.
I still need an oil change and brake flush and a once over inspection but I hardly think it merits the $900 fee. I'm thinking I'll do the air/pollen filter and spark plugs me self. The only reason I was leaning toward the dealer was to have the records which so far indicate that only Porsche mechanics have touched my car.

what's a good source for OEM plugs?

Hi,

Call NAPA, they stock em and no S/H. I wouldn't put much stock in only Porsche Mechanics wrenching on the Car. Bye and Large, they're OK, but they have their share of Knuckleheads as well. This is so easy, it doesn't pay to have someone do it - took me 20 min. I think and I know it's done right! Good Luck!...

What Jim said (especially about sticking with the OEM plugs) but the hex bit is 5mm (to answer the question marks). John linked my site and I show how to replace them with the wheels off but you don't have to take the wheels off in order to change the plugs. I do a brake inspection at the same time so it's just easier for a fat guy with fat hands to reach in through the wheel well.

I have the OEM part number for the Bosch plugs on my site if you want to look around and find them online.

When I did mine five clicked and one no matter how many times I tried to re-insert it wouldn't make(or maybe I couldn't hear) the clicking sound. If the CoilPak wasn't installed correctly it wouldn't it have triggered a CEL?

Definitely remove the tire. It makes it much easier to see what you're doing - you don't have to phyically get under the car if the tires are off.

Thanks to you folks, job was done in a falsh, great info, I feel like a dunce asking the question now. I used the (7) heat range plugs, no anti seeze, and found one damaged 0 ring on one of the tubes. Not sure what my dealer would have charged, but I don't think it would have been cheap. Thanks again!

what brand of anti-seize should be used?
