[volzalum 280]

Which Spark plugs are you running in the 330 Black Scorpion (Serial Number OW692XXX)?

 

The mercury part is 884019001 or AC 41-993 @ $15.95 per plug (platinum marine)

 

Other plugs:

 

ACDelco 41-993 for $6.25 each (platinum)

 

NGK IZFR7M for $12.30 each (iridium)

 

NGK TR55GP for $3.15 each (platinum)

 

NGK TR55IX for $7.83 each (iridium)

 

NGK TR6IX for $8.48 each (iridium)

 

Autolight APP605 for $5.52 each (double platinum)

 

Denso IT20 for $11.99 each (iridium)

 

E3 E3.54 for $5.95 each (non-adjustable gap)

 

 

So there are alot of choices ... I am leaning towards the NGK TR55IX, but would like to know what others are running ... I hate to pay the mercury price unless there is a real reason to need to ...

I run the Mercs OEM through mechanic, I just keep it simple, but if you want to change I would go for the Denso or the TR6IX. I run NGK in my vehicles and wish I would have a long time ago. Make sure they wouldn't void any kind of warranty though, you know how that could be, something not related but could cause headache.
