I'm curious who here has ran a step colder plug and what was your experience with them? What mods are you running?
This seems to be a topic of debate with these engines, with some people saying a range 7 plug is absolutely a good idea for cheap insurance on a "not stock" setup while others are of the mindset that the factory range 6 is more than adequate.
I ran NGK Ruthenium HX plugs on my '17 Sport and it seemed to run really well with them at all times. Now I'm thinking of tossing a set in the ST but going one step colder for good insurance especially considering these Explorers turn up alot better than the 3.5EB
Right now I'm running a Livernois 93 pump gas tune and it for sure made a considerable difference in performance and acceleration over stock. I have a few other modifications planned such as a complete CAI setup, exhaust and Whipple intercooler.
I've always been of the mentality "Run the HOTTEST plug possible that doesn't result in detonation". But I typically work with N/A engines. I have a 550+hp LS3 running just fine on TR6 (NGK range 6) plugs but 0psi vs 20+psi isn't exactly apples to apples.
FWIW I know that fuel type also plays a pretty big role in this discussion. As of right now this is just a fun daily to haul ass down the highway with and some occasional track time. 93 pump gas is likely going to be the only type of fuel I'm running.
