Spark plugs eh.... I use NGK, but have been known to sneak in Bosch super plugs. don't be fooled by thoes multi electrode plugs, its a waste of money. And make sure you gap the plugs properly, and put on that dialectric grease!

[quote]I've heard that using "silver" ones are the best ones to use.
I haven't been able to find them though. Anyone have a source for them?

Couple of years ago on the email list several people complained of cold start problems when using the Bosch silver plugs, the copper plugs work fine.

IMHO:
Copper - works great, cheap
Platinum - works good, lasts long time, multi-tip units not for turbos or aftermarket ignitions and coils
Silver - best conductor, use on race engines, does not last as long as copper, cold start performance is reduced slightly (3-4 revolutions)
I ran through a set of Bosch Silvers in ~1 year (dropped one, but they needed to come out anyway). I now have BERU Silverstones (can you guess why
) and really like them - they do take a couple more cranks to get going once broken in, but they look great after ~6 months of use with MSD 6A, Blaster2, and ~98 octane.

A couple of years ago the motorcycle magazines tested the "fancy" plugs and determined that they were basically "snake oil".
I just use NGK and change them at 6 months at a buck a plug.

I agree the NGK work fine and are reasonable. I have the Platinum 4 plugs currently. They state on the package that if you don't notice a "noticable" difference after installing these plugs, that they will buy them back. Well I've had them for a year now and the only noticable difference is that I'm missing $20 bucks from my wallet.
Use the NGK!!

Spark Plugs - Install With Threads Clean and Dry

Part Identifier Number

Subject:
Spark Plug Thread Lubrication
ATTENTION: Service manager/Service Technician
This bulletin supercedes Technical Bulletin Group 28, Number 78-03, Book A, page 297.
Models Affected: All
Concern: Spark plug thread lubrication.
Service Information: The Carrera 2/4 Workshop Manual Vol. 1, page 03-11, in the section on replacing spark plugs states "Do not use any lubricant on the (spark) plug threads."
This procedure now applies retroactively to all Porsche models. All spark plugs should be installed with the threads clean and dry.
The torque specification is unchanged: 25-30 N-m (19-22 ft.lb.).

I must say I don't normally use Jap parts on my P-car but NGK plugs are just so good, that I use them in every single car I own.
One comment on the platinum plugs. If your car wasn't designed for them they may last a very short time. I put them in a Ford (please, I just don't want to talk about it) one time and had to yank them out 5K miles later -- completely spent!
