Inquiring minds wanted to know how advisable or inadvisable it was to use Platinum type spark plugs with MSD ignitions, so I asked. MSD reply below:

Dear Sir;

Platinum and other "hype" type plugs tend to run too hot and can cause them to prematurely fail. We suggest using a standard type plug with a heat range or two colder.

Thank You,
