Since vehicles with direct ignition systems were first introduced in 1988, an ever-increasing number of new cars and trucks are being manufactured using coil-on-plug (Cop) technology for ignition systems. Since 2007, more than 70 percent of all new vehicle production utilized coil-on-plug technology, and today more than 30% of all vehicles on the road use coil-on-plug. These complex engines require ignition components that deliver maximum spark, provide long life and meet or exceed original manufacturer specifications. Autozone duration coil-on-plug insulators are a cost-effective solution to replace insulators that fail due to normal wear and tear or are damaged during tune-ups. They are designed specifically for the replacement of coil-on-plug insulators in domestic and imported automobiles and trucks.
