NGK V-Power Spark Plugs come with unique V-power design that directs spark to the edge of the electrode where it develops more rapidly to improve ignitability unlike other OE products.
Denso's Premium Class Double Platinum Spark Plugs provides the most durable and reliable performance by incorporating the latest and most reliable design and materials for a spark plug. Denso applied platinum to both the center and ground electrodes with superior resistance to erosion and corrosion which enables Denso to create a spark plug capable of consistent, extended operation in excess of 60,000 miles.
Premium Class Iridium Spark Plugs by Denso are fast becoming the standard for today's high-tech engines. Employing a revolutionary 360 degrees laser welding process, Denso has created a spark plug unlike anything on the market today. The spark plugs are designed for durability under the most extreme conditions. Denso's patented Iridium alloy is 6 times harder and 8 times stronger than conventional platinum and can handle temperatures in excess of 4,000 degrees Fahrenheit.
Bosch Super Class Platinum Plus Spark Plug reaches self cleaning temperature faster for quicker starts, smoother acceleration, and increased fuel efficiency. Metal glass fused resistor allows for maximum interference suppression while the ribbed insulator design prevents misfires due to current leakage.
AC Delco Iridium Spark Plugs allow smaller, more efficient electrode designs for improved cold starting, and quicker acceleration. These spark plugs are constructed from top quality materials to help the engine run clean and longer. They also engineered to high standards and tested under extreme conditions to exceed OE specifications.
