Review on 🔌 NGK (8660) RC-XX89 High-Performance Spark Plug Wire Set by Kevin Hawkins

I fitted this kit to my Hyundai Coupe 2005 1.6 CC after 156,000 km with the standard kit. Equipped with the NGK Iridium IX kit, fits great as an OEM and even looks a lot better! The vibrations are gone, the engine sounds like a sleeping cat, very, very, very smooth acceleration and a noticeable improvement in fuel consumption, surprisingly stable acceleration at high speeds. The improvements are really noticeable. Definitely a great upgrade and investment, especially over the long term
