They look quality. Needed to be gapped, always check! 2003 Crown Vic with 45K. Gas mileage improved from 18 to 22 at 80 mph. I think the old plugs were the originals. Idle is smooth and acceleration is improved.

Over the time of me owning a vehicle I never encountered a plug failure so as to why I purchased this product, why not? MSD is a excellent company and Summit makes one stop shopping accompanied with fast shipping an easy way of doing things
