I took my raptor to Fastlane in Houston to get the phase 2 Roush phase2 SC installed. I asked them to change the spark plugs with the install. They were not very polite. Not very good customer service , charged me $1000 to change them, long story short when I got the truck back it wasnt running right I told them they said they would take a look at it they never did. I had the plugs pulled and it was as clear that they had not been touched(see pics). My question is I bought the NGK ruthenium HX plugs and took it back to Fastlane to get them installed and they’re telling me that they don’t need to be re gapped that they need to go with the OEM gap which is .044 because it’s not a colder plug although I know it is a colder plug. Is there any one out there who has definitive data in terms of the gap The plug needs to be with the Roush phase 2 supercharger and a NGK ruthenium/ HX NGK spark plug. ?
