Denso 3139 COPPER SPARK PLUG - 4pcs

DENSO 3139 COPPER SPARK PLUG; Copper; U-Groove Conventional; GAP .044 (FOR MOTOR VEHICLES ONLY)

DENSO's patented U-Groove spark plug enables complete combustion by allowing the spark to fill the gap created by the U shape. The ball of fire created in the U-Groove develops a larger and hotter flash front that virtually eliminates excessive fouling and erratic starts caused by poor petrol mixtures.

Even DENSO's "standard" spark plug is something special. The innovative design that helped to make DENSO spark plugs famous, the U-Groove plug employs a unique, channeled ground electrode designed to generate a larger spark nucleus at the point of ignition. Greater spark energy than ordinary plugs means improved flame travel, producing more complete, consistent, and efficient combustion.

Features:

• 100 percent pre-fired to ensure reliable operation
• Copper core center electrode for superior thermal conductivity
• Unique five-rib insulator reduces flashover
• Dual copper and glass seal bonds the center electrode and insulator together for a gas-tight seal.
