Denso W16EX-U13 Spark Plug
Denso W16EX-U13 Spark Plug Standard
Stock # 3029

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.

  • 100 percent pre-fired to ensure reliable operation

  • Unique five-rib insulator reduces flashover

BENEFITS

  • Patented U-groove ground electrode design fires leaner mixtures than conventional plugs

Excellent purchase. I knew I was getting the right part due to the website set up and it came fast. The price was a plus too as it was far cheaper on autoplicity versus any other site I found.
