My plugs look worse than that after 5000 miles.Did seasonal tire rotation from summers -> winters (on seperate rims) on my wife’s 2016 Mazda CX-5. She doesn’t drive it to much, 108K kms since new. Also changed oil (Kirkland 0W20 4.5L and OEM filter). Also did spark plugs, OEM NGKs from Rock Auto. Didn’t realise I needed a 3/8”/14mm spark plug socket, so had to whip out to Canadian Tire and buy the last one they had for $8.99 CAD. Worked perfectly. The old plugs looked pretty good in my opinion. View attachment 245085
