Since the 993 ignition system is weak to begin with, these plugs can be better than the stock plugs provided they are selected properly. If the proper heat range is run, then the plug will run hot enough to burn off deposits including techron. The factory plugs have 3 ground straps and are really antifouling plugs and not performance plugs and Porsche has a history of installing plugs that are too cold into their engines. Asking your local autoparts store for advice on spark plugs is like asking McDonalds for advice on prime rib...unless of course you want to know how the latest muffler bearing can help put bling in your ride.

If you can't really feel the performance difference between the factory plug and a Platinium plug for street driving only, what would be the point in installing them?

Do you have the respective P/Ns for all the plugs? I would like to just order by manufacturer P/N then waste time going thru the 21 questions at the parts store when its time to replace the plugs.
