Been running the same ones since 28K. Currently have 51K. Plugs have seen a lot of tuning miles, misfires, flooding due to misfiring injectors. Still going strong, still not misfiring. Lol. You're good til at least 60K for sure. Maybe even more.

I run the Brisk RR12S and change mine every 5K miles or less simply due to how often my car is apart. I would run the same plug if I were you and change them every 10k

Mine are changed... EVERTIME I sent it to Katech to have more work done to it !!! At this point, that's once a year since buying the car new! Hahaha I just had to say that, as it even sounds funny to me when I say it! But, I only drive my car 3K a year too.

I just had a 4 year service done on my car, 22k kms on it. This is what the single plug they pulled looked like. Decided to change them as they are really not that expensive.

Spark plugs and oil are cheap, relative to the cost of the car... use the best and change often. Or, sell the car to someone who will.
