So I was wondering if it was time to change the spark plugs.
Cause i bought the truck with 60,000 miles and I'm not sure exactly what was done to it, as far as maintenance.
Through researching I found that the factory used Denso on the left side and NGK on the right, although the plugs had 2 contacts on it. So I'm not sure if they were original or not.
I've attached a picture. Thanks
