Plug choice for my 80 911 SC

[nixter]

I've done searches and found quite a few different answers for which plugs are best for my car. Is there a gerneral consensus on this issue? My car is stock.

Thanks,

Nix

Bosch or NGK copper plugs,cheap and work fine,no need for platinum plugs.

I put a set of NGK-BPR6ES plugs in my '72 two weeks ago after doing some searching here. 6 of them for $10 from the local autoparts store and everything is working nicely.

Do you have a good plug removal tool?

[nixter]

No, I need to get one.

Thanks guys,

Nikolai

Bosch copper, heat range 7 in my modded 80 engine. If you are stock try the recommended heat range first. Then vary from it if you make mods or encounter problems.

[nixter]

I see, thanks. Any idea what the heat range for stock would be?

nixter,
Do you have the original tool kit? The supplied sparkplug wrench in the tool kit is the best tool to remove or install plugs. I bought a special ratchet and sparkplug socket to do the job. After using it several times, I discovered the tool supplied by Porsche is far and away better. Mine uses the socket and a 10 mm allen wrench, also supplied.
With this setup you don't drop the socket into the motor.
If you don't have the tool kit, you may find the sparkplug tool on Ebay for around $15.
Remember, when installing new plugs, just snug it up and lightly tighten with one hand. I use a very small amount of grease or never seize on the threads.
I use NGK BP7ES in my 2.7, I agree copper Bosch or NGK work best.
Have fun,

I'd go with the OE plugs from either.

Thanks for the info guys. Unfortunately I do not have the origainl toolkit, even though I know the only 2 other previous owners. The one who probably lost it is also my best friend, great guy but a total scatterbrain!

Can I buy one at an auto parts store or is it a Porsche specific tool?

Porsche apparently recommends that you not use antisieze compound on the plugs as this could interfere with proper grounding between the block and plug. Maybe some have done this, however, with OK results. I have always followed the factory on this one.

If you search you can see some of the tools posters use. The factory one works really great, but you would have to get it at the dealer. You may find one in buy/sell venues, swap meets, etc.

Here's a thread on factory toolkits:
Whats in Your Toolkit????

I'd check Ebay as they're always on there.

Here's a pic of an '85 Euro 930 kit. Many of the tools will be the same.
