It would all depend on your tuneup. If you are rich you will be changing plugs out more often. If you are dead on then you will not be changing your plugs as often. There is not a real dead set answer. It would all depend on your tuneup.

I change mine after a heavy night of racing. I got lazy and left my current ones in after racing, car sat up 2 weeks, now idles like crap.... Happened before, changed plugs, problem solved.
How do your plugs look on your N/A tune vs Spray?
And then there was silience lol.

Just got the AFR where I wanted it on the wide band, made sure that the VE error % was in line with what I wanted to see(no more than 1-2% in either direction) and that total timing was where I wanted it and no knock was present on motor.
On nitrous that's a totally different story though
I will say that having a dyno that we can load with however much % needs to be accounted for vehicle weight just like running your car at the track would will make plug reading and dialing my motor in SO much easier than having to do it all at the track.
That doesn't mean I won't still read my plugs at the track, but as far as getting the tune-up close it's a godsend.

I was running TR6's at the time, with a ZEX wet kit with a 75 shot on it.
[Purchased from Nitrous outlet, by the way]
I could have put them back in.
My afr at idle is 14.7-15.1.
At cruise, with no load 14.5-14.9 or right around there.
Ran TR6's for 5 or 6 years, and it wasn't untill I went with nitro Dave's wet plate that I went to a BR series plug.

To be 100% honest I have never read my plugs on motor!

One thing I have learned a lot over time is that there are 10 different ways to skin a cat or run a race car. Do it however makes you confident in your testing and results you get from them.

Ha ha. You read to much into my post.
I didn't mean I drove 8,000 miles before checking them.
I meant that the last set I put in, stayed in, untill I changed to the plate kit.

I understand what you mean now, and what you meant before you ninja edited your post LOL!
Does the pill size dictate how often you should/need to replace plugs? So far I've put about 5 bottles through my car on the .052 pill with the same plugs.

If your tune-up is correct and it is indeed how it should be then I wouldn't worry about changing them aside from track use.
I would say if it's a street vehicle that is driven a lot on the street then change them when you get to the track. If you're going to be in a money race or something and you have the opportunity to change them on the street then do it.
Moral of the story don't tell the auto parts people you own a sports/race car lmao.
Yea I did that and after about the 3rd trip to the drag strip they started asking me, what are you putting these in...well I lied and said I was putting them in my S-10 LOL and the guy behind the counter that wasn't helping me said, "Hey didn't you tell me one time you were putting these in your camaro with nitrous"? LOL it was all downhill from there.

It says right on the receipt that they have a 1 year warranty so it's not really that big of a deal.
I kept my receipt and my original box and walked up to the counter and placed all 8 next to the guy and said "well I don't know which one it is, but these cost me a tow truck ride and $75. One of them is messed up and I don't know which one but I would like to have them replaced under the warranty."
They said oh ok, no problem, let's make sure we have them in stock and we can exchange them for you.
5 minutes later I walked out with a new set of plugs for $0 and a fresh 12 month warranty.
Lol they haven't said anything yet but I've only exchanged them once...
