ACDelco Iridium Spark Plug is a high-quality iridium spark plug engineered to help save fuel and provide excellent vehicle acceleration.
The core electrode is made of copper with iridium tips, precision-welded using laser technology, and has a platinum pad ground terminal.
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.
