Review on 🔌 NGK 58410 RC-EUC071 Spark Plug Wire Set: Optimal Performance and Durability by Antonio Liu

. I installed these wires on an 02 ML 320 (95,000 miles) after getting an offer from a mechanic for almost $800 for 12 spark plugs (two per cylinder) and separate wires ONLY. if needed. Under $300 for parts with all new cables. I used Denso Iridium plugs in addition to these wires and got to 2mpg quickly. The steel toes weren't as long as the original wires, but I attribute that to things being less durable. compared to 10 years ago. My only other complaint was that they only gave you a VERY small packet of silicone grease. For 12 cables and connectors you will probably need 4 packs of this size. With all that being said, I wouldn't hesitate to buy them again.
