My Ford mechanic installed Bosch Spark Plugs four years ago. I found a forum that said these plugs won't run in f150 trucks. The truck idled so bad I thought the motor would fall out. The mechanic fulled all kinds of codes and said it would cost huge money to fix a manifold leak. After installing the NGK plugs it has never run better. Also noted these Bosch plugs were OK for the first 30,000 KM and failed the last 25,000 KM.
