Platinum spark plugs
Discussion
Well, when I was running a supercharged Mustang, I was advised against platinum plugs. I was told that they are not recommended in any forced induction system. From what I remember it was due to the fact that you are trading a stronger spark, which is needed in forced induction, for longer life. This was a few years ago though and maybe by now the newer platinum plugs are more equal in performance. I would research some modern factory forced induction cars to see what they come with and what is recommended in the area.
Personally, I would rather just replace the plugs on a regular basis, thereby spending an extra $20 than go to a platinum plug.

Hi,
There's really nothing 'better' about platinum plugs in terms of their performance. The platinum electrode is simply self-cleaning due to the much higher heat they maintain and the chemical inertness of the platinum to combustion by-products, so they last lomger.
They run hotter, which in a turbo environment isn't always a good thing. Personally, I'd stick to the regular plugs which are more than adequate. I wouldn't want my plugs to stay in the car for 50k-100k mi. no matter what material they are made of. Happu Motoring! Jim'85TE

My NGKs in my '89 non-SE lasted only about 20,000 miles. The Bosch platinums didn't do any better. The center platinum electrode didn't disappear as on the NGK but the ground piece did. The latter part isn't made of platinum. No performance difference I could notice. The plugs on my Europa lasted only 3000 miles. Must be something about Loti.
