Review on Federal Wires 3164 Spark Plug by Jerome Dasilva

I recently purchased these spark plugs for my automotive and they have proved to be efficient and durable. As a result of my tests, I determined that they have significantly improved my ignition system's performance and fuel economy. However, they are a bit PRICIER compared to other options in the market... Nonetheless, I highly recommend them for those looking for quality ignition parts..
