Amazon Verified Purchase(What's this?)

This review is from: NGK Spark Plugs box of 4 (Sports)

I purchased these plugs for my 225 Mercury. They are the best you can buy. The price on Amazon was competetive enough with local stores that I didn't bother driving into town to purchase a set. They arrived on time and in perfect condition. I installed them the next day and have been using them for quite a while and will probably be using them for quite a while longer. NGK plugs are great.
