TR5
If you had forced induction or a big cam, TR6

TR5. You will lose power on a stock car if you go with TR6

With NGK, the lower the plug number, the hotter the plug. Higher the number, the colder.
Per NGK: An unaltered engine will run within the optimum operating range straight from the manufacturer, but if you make modifications such as adding a turbo or supercharger, increasing compression, timing changes, use of alternate fuels, or sustained use of nitrous oxide, these can alter the plug tip temperature, necessitating a colder plug The OEM Delco plugs on our v8 cars are generally considered to be in the '5' heat range, when compared to NGK. But per NGK themselves, 'The heat range numbering system used by spark plug manufacturers is not universal.' NGK also says 'A good rule of thumb is, one heat range colder for every 75–100hp added' - of course this isn't a concrete rule, just a rule of thumb as they explain. Datalogs would need to be examined and compared to truly determine if changing to a colder/warmer plug is beneficial and when it's most efficient/safe. But for me, my previous tuner DynoSteve recommended I move to a colder plug, the NGK TR6IX specifically, after I went with headers, catless, CAI, throttle body, and his tune. After I went with a cam, had my heads milled, and a more targeted tune for those mods, my current tuner said I would be perfectly fine to stay with the TR6IX's. So based on the fact that you are stock and also running the stock tune, you may run into plug fouling issues if unnecessarily running a colder plug, since the plugs likely won't be able to get hot enough with the current stock timing and fueling settings to self clean. This may also lead to inefficient/partial combustion. Sorry to make this so long, but it figure it is best to also try to explain the 'whys' rather than just tell someone what is best. NGK has a decent short explanation on their website at this link, which is where this info comes from: https://www.ngk.com/what-is-a-spark-plugs-heat-range-2

Hey thanks fellers. I don't pretend to know everything and am always learning from the smart guys here, but I do like to share what I do know or at the least to try and help someone find an answer.
We gotta do what we can to keep this site alive, and the only way to do it is to keep people feeling that it has value.

Hi all, can I jump in late here with a couple of questions? Looking for plugs for my 2010 2SS. I wanted genuine AC Delco 41-110 but seems there is a lot of fake copies made in China ending up on Ebay. So....I'm going to run NGK instead. The only mods on my car are cold air intake and long tube headers. NGK themselves say this plug NGK IZTR5B11, but the gap is 1.1 which = .043, when the gap should be .040. Will 43 still be ok or does it have to be 40? Is anyone else running NGK Spark Plug IZTR5B11?

Does the car have a tune on it for the LT headers?? If so, when we did mine with those mods I ran the NGK TR 55's.. Straight out of the box. .040.Ran great.

Still running stock plugs as my 2013 2SS/RS has only 24K miles on it. LT headers, CAI, Borla exhaust and Jannetty Racing tune. Runs great. So are the stock plugs .040?

Yes, Camaro manual says 0.40. Trying to decide between NGK TR5, TR55 and TR6. I understand TR6 is more for supercharged cars etc but one mechanic told me because my car is not stock and is running CAI with LT headers and Cat delete I should go with TR6. Thanks for the reply.
