How Do These Spark Plugs Look?
I pulled out my OEM spark plugs last week at 69958 miles. I replaced them with some NGK Iridium premium plugs (didn't feel like waiting until 120k miles). How do the stock ones look? The right two (cylinders 3 and 4, right?) looks like it's has more deposits/wear on them than the left two. What do you guys think, anything I should be concerned about?
First pic is of all four. The second and third pics are the left two cylinder's plugs and the right two, respectively, with flash. The last two pics are the same, but without flash. |
