Whats the latest suggestions on plugs for tune/ downpipe?
As the title says,was wondering whats the best rout that people who are modded (tune/ Down pipe) taking for plugs
Are updated stock ones still the best option. or is there a better option?
Gaping stock or (please provide suggestion)

NGK 95770 ILZKBR7B8DG gapped to .024 are working great for me. They’re one step colder than OEM and I’ve gotten some performance gains at the track that I can only attribute to the plugs since there were no other changes.

Am also on tune/ DP combo so debating on what plugs to get...
When you say the plug is one step colder then stock, are you referring to the updated stock plugs?

The plugs I just replaced were from my tuner and were two steps colder than my stock plugs. I didn’t think two steps colder was needed for just tune and DPs. I have no idea what specs (if any) have changed on the factory plugs from 2012 to 2015 as I’ve only heard speculation with no evidence.
