Has anyone purchased PT# M-12405-35T, installed them with no issues or verified that they are in fact the same or similar to the SP-542 plugs? Thanks ahead of time for any responses.

I indeed have. They are just the sp-542 plug in a kit of 6.

So, what’s the benefit of using these over the stock spark plugs?

I recommend checking out the SP-542 thread. There you will find all the answers.

Ok. Thanks. BTW, does the Raptor take 12 plugs or 6?

 

[SRPRACING]
