Bought some cheap spark plugs from autozone the other day well yestweday lol but just need some opinions on then. So in pretty sure theyre 104 autolite spark plugs not sure if the 104 means anything but says it oj the box somewhere. So has anyone ever heard of these or used them in a sevillw sts?
If no ones used em will they be fine running ij my car or should i upgrade them to the more expensive ones either way its bot a big deal ill spend the extra 20 or 30 bucks to gst better quality but then again also if these are just as good would rather not bave to run out to autozone again unless need to. Theyre 104 autolite copper coated or something
Thanks fof any input
