Product Information

IRIDIUM SPARK PLUG
  • Iridium (extracted from meteorites) is far superior to platinum-6 times harder, 8 times stronger and able to take temperatures up to 1200° F hotter!
  • Iridium center electrode tip is the world's smallest (only 0.4mm diameter) to produce the hottest, most concentrated spark while requiring the least voltage (5,000 less volts to fire than conventional spark plugs!)
  • For performance or everyday driving, this plug is the one!
Because of its patented technology, the iridium power plug outperforms any plug today...including the popular platinum! It fires better and incorporates all the top features below to maximize performance even under the most extreme conditions-you'll enjoy more horsepower, faster, easier starts, less misfires under heavy loads plus better fuel at all times! Iridium is the most corrosion-resistant metal used in plugs today...it can survive the super-high temperatures (up to 4400° F) associated with high-performance ignitions and special fuel systems (turbo, supercharger, nitrous, etc.).
MORE HIGH-PERFORMANCE FEATURES THAN ANY OTHER PLUG!
PREFIRED. For highest quality!
5-RIB DESIGN. Prevents flashover and decreases voltage loss.
INSULATOR. Purified alumina power for exceptional dielectric strength and thermal conductivity at high temperatures.
COPPER-GLASS SEAL. Ensures proper heat is maintained and hot combustion gases are excluded.
COPPER-CORED CENTER ELECTRODE. For superior thermal conductivity.
LASER WELDING. 360° seal helps prevent electrode wear.
U-GROOVE GROUND ELECTRODE. Allows spark to develop into a larger, hotter flash front for most complete combustion-bad starts caused by poor fuel mixtures are virtually eliminated.
PATENTED IRIDIUM CENTER ELECTRODE. Tapered cut improves firing performance by reducing quenching.
