Spark Plug Replacement for R030010

[freddiefokker 2]

Hi:

I'm winterizing my 07 Typhoon C4 and I thought I'd treat her to some new plugs.

What's a Bosch or NGK equivalent to PCM R030010? I believe the AC Delco equivalent is AC41-101.

I've searched this forum, the NGK site and the ACD site....

Thanks

What motor are you running in this 07 C4?

I have the Mercruiser Black scorpion 330 and I went with the AC Delco's the manual called out. The factory ones lasted a good bit so why change brands. I ordered mine on line because it was about 1/2 the price.

I thought those used

MR43LTS gapped at .45 or Platinum 41-932 or 41-993 @.60

Either way even if my numbers are wrong I would stick with AC for a Chevy motor, autolites on a Ford keep the NGK or ND's for the imports and the Bosch plugs for the germans. For whatever reason the manufacturers OE stuff seems to run the best for me.
