• High Performance: Spiral core wires offer low resistance with superior conductivity of the spark charge，ensuring proper spark delivery to the spark plugs, while maintaining great EMI/RFI suppression, without interfering radio frequency. Can improve ignition performance and smoother engine start
• Premium Quality: 10.5mm ignition wires have a high dielectric strength insulator and heavy glass braid, with heavy-duty silicone jackets and high-temperature black boots with superior dielectric and heat performance to resist damage from heat and abrasion
• Easy Installation: Make sure your car's engine is cold before you starting, remove the old spark plug wire set, and then install the new high performance spark plug wire set, once properly aligned the wire will connect easily with just a gentle push and twist
• Wide Application: If your car has problems such as car sharking, difficulty starting, slow acceleration, increased fuel consumption, etc., you may need to replace a new set of spark plug wires
• Package Includes: 8 PCS 10.5mm spark plug wire
