ACDelco Iridium Spark Plug is a high-quality iridium spark plug engineered to help save fuel and provide excellent vehicle acceleration.
Reduced sparking voltage and greater corrosion protection.
Tapered center wire electrode with a platinum pad reduces the firing diameter and helps improve firing efficiency by concentrating and directing the energy needed to fire the plug with less voltage.
Longer life and improved efficiency, with up to 80,000-100,000 km service life.
The tip of the core electrode is iridium, a small needle (0.4-0.6 mm), which makes the ignition performance better than conventional and platinum spark plugs, resulting in better acceleration.
Ribbed insulator notches help prevent current leakage or short circuits.
The central terminal is copper, providing good heat dissipation and prevents overheating, which can cause damage to the engine. • The nickel-plated shell provides high thermal corrosion resistance and good adhesion protection.
The gap between the core insulator and metal sheath has a wide opening to help prevent sparks.
Uses high-quality ceramic material for better heat insulation and protection.
