Product Details
Denso W20EX-U13 Spark Plug
Denso W20EX-U13 Spark Plug Standard
Stock # 3064

Spark plugs are not all alike. With the world-famous DENSO U-Groove spark plug it?s easy to see, thanks to its patented U-shaped ground electrode. The U-Groove forms a channel for the spark nucleus to form at the instant of ignition, limiting quenching to generate a more potent spark. The premium features don?t stop there: DENSO?s distinctive five-rib insulator in purified alumina prevents leakage and flashover, while dual internal copper-glass seals and a copper-core center electrode with nickel-alloy tip assure reliable spark delivery. To keep your engine running smoothly, its spark plugs must fire 25 times a second or more. If just one spark plug skips a beat you?ll know it instantly, with rough running, poor acceleration, and reduced fuel economy. DENSO U-groove spark plugs combine dependable performance and superior value.

FEATURES

  • 100 percent pre-fired to ensure reliable operation
  • Copper core center electrode for superior thermal conductivity
  • Unique five-rib insulator reduces flashover

BENEFITS

  • Patented U-groove ground electrode design fires leaner mixtures than conventional plugs
  • Precision machine-rolled threads reduce seizing and cross-threading in delicate aluminum heads
  • Wide range of part numbers for thousands of applications, including classic and collector cars
