Review on NGK 7252 Spark Plug by Troy Kocur

Spark plugs work great in my Cherokee 4.0. They come out about 0.038 apart, but that's not very important. I gave a bad review because the delivery quality was terrible. They were in a folded piece of cardboard that fell outside of each box and was smashed. I think whoever packed them doesn't understand that they are ceramic and fragile. However, they arrived intact, on time and fitted well. I mentioned the packaging just in case someone needs it ASAP and doesn't want to risk getting cracked spark plugs. They should be surrounded by foam or air foil so they don't break next time.
