No nitrous. Naturally Aspirated. Motor was pinging the other day so I wanna run the TR6 to try to help. New gas would probably fix it but I'd rather overdo it.

Yep, when I was N/A, nothing but TR55's at .055" and never had a problem. Shouldn't need TR6's, those are a step colder for nitrous and FI engines.

There was a service bullettin put out for older pre 2004 trucks about a change in plugs and therefore they need a .040 gap. Im not sure if it applys for NGKs?
