7 heat range
I googled this and everyone is talking about using the r5671a-7 in there boosted ls6. Had a few questions.
1- how will this plug work when it’s not a tapered plug and has a washer
2- would a br7ea be a better Choice
T Hanks in advance for the help
Im right around 650 at the wheels on 12lbs of boost

tr6 will be fine at your power level, I used those gapped at .035 and they were good up to about 800 and when I switched to e85 they started breaking up at high rpm so I switched them out for br7ef gapped at .030 and haven't had that issue since
