What's hot

• 12-month/12,000-Mile Limited Warranty
• ACDelco Iridium plugs require reduced ignition system voltage which increases lifespan of costly ignition system components
• Smaller, more efficient, Iridium electrode designs are to improve cold starting, quicker acceleration, and lifespan

• Features a copper-core center electrode
• Engineered to high standards
• Assured high quality and dependability

• Wire-wound, stainless steel alloy conductor for maximum spark delivery and RFI suppression on most applications
• Thick silicone outer jacket for excellent heat resistance
• Designed to match Original Equipment wire sets in critical areas such as cable length and diameter, terminal design and insulator position

• Fine platinum tip reduces required voltage
• Constructed from durable material
• Extremely durable under high heat

• Engineered to high standards
• Helps the engine run clean and longer
• Tapered center wire electrode with a platinum pad reduces the firing diameter and helps improve the firing efficiency
