Review on Denso 671 4247 Spark Plug Wire by Maurice Malek

This is the lowest quality you can buy. The connectors were covered with rubber adhesive which I had to manually remove before installing (took about 30 minutes). They work great in the car, but they feel so cheap and flimsy that I expect them to go bad quickly. The metal terminals are about half the size of the original spark plug leads I had. So you get that, but it's a much less solid connection than the automaker envisioned. I only used them because my old ones couldn't be driven in the car, otherwise I would have returned them.
