ngk TR6 is stock heat range for stock z06
Read the forum a lot and kept hearing tr6 ngk is step colder for cammed z06s...I called ngk and they said tr6 is stock heat range for a stock z06. So I put in tr7ix . Chose iridium because stock plugs were iridium... I had tr6 in the car. The car seems to like the new plugs all around...My tr6 were only 3 months old and 1,000 miles on them..Just thought id post because I thought tr6 was colder .

interesting. I know everyone including me has used tr6's forever... I don't know much about the difference it would provide but curious to do more research... being a GM tech I normally use the stock ones in cars and all the performance builds I do I use tr6's but maybe I need to change it up?

I went to TR6 ix. Need to get it dyno tuned again. Found out my car had TR5's in it, which is too hot even for stock. Made 544 rwhp on TR5's (before I found out) and it couldn't take much timing.

That's why I am using Denso IT-22.

Stock plug isn't NGK but it would be a ~6 range in AC delco form.

Typically we run 11.4 to 11.6 compression on most street setups and with that cam I would generally run a 7 heat range plug from NGK.
