I used the SP-548 for my replacement. At the tyme I was told these were the OEM replacements for my 2012 Boss but I didn't get the part number from the manual. They work just fine.

Thanks guys for this info

What if i want to go for ngk or any other brand ? What kind of change will it do to the car ? Does it affect the car’s tune ?

And why do people go for iridium or laser plugs over the oem ?? Does it make any difference at all ??
