I'm getting ready to do some servicing on my '89 Carrera 3.2. Regarding sparkplugs, what are you guys running? The stock/standard Bosch or? I was looking at the Perforance Auto catalog and saw the Nippon Denso's @ $11.99. These plugs come in most Japanese sport bikes. Any good in our cars?

I'm assuming that Mahle is the OE manufacturer for Porsche filters?

Thanks,

David
