Review on NGK 52048 FDZ066 Spark Plug by Jere Mosley

Quality spark plug wire set. Perfect length, really excellent performance, I believe they are more durable than the original Motorcraft wires. Made from ultra high quality materials. My Explorer SUV has greatly improved thanks to these wires. The only comment I have is the terminal boots. It's quite difficult to insert and make a "click" sound indicating proper insertion. I think the boots should be quite large or have some kind of base to make it easier to pick them up with your hands and put them in the spark plug. I bought this ignition cable set and NGK Iridium spark plugs. winning combination.
