#ad
Sixity Auto #ad - Ensure reliability: these spark plugs feature cold-rolled threads to prevent damage to the cylinder head and trivalent metal plating that provides superior anti-corrosion and anti-seizing properties. Choose consistent combustion: featuring improved performance over OEM and standard plugs, the solid copper core of the V-Power Spark Plug provides superior heat dissipation, conductivity, and a broader heat range for increased fuel economy and lower emissions.

Prevent flashover and leakage: the unique five-rib insulator prevents spark flashover that causes harmful misfires while the triple gasket sealing process virtually eliminates gas leakage past the shell.

Install easily: ngk v-power spark Plugs feature an insulator design treated with corrosion-resistant plating to ensure ease of installation and removal. Trust in oe quality: providing great ignitability and performance over conventional spark plugs, these OE- and racer-approved spark plugs have an alumina silicate ceramic insulator that provides superior strength and better heat transfer.

8 pc Denso Standard U-Groove Spark Plug for Dodge Ram 1500 4.7L V8 2002-2007 Tune Up Kit

#ad
Sixity Auto #ad - Gain greater fuel efficiency: the u-groove ground electrode was developed to improve ignitability for increased efficiency in emission gas purification and fuel consumption. Enjoy trouble-free performance: the unique five-rib insulator reduces flashover and decreases voltage loss while the dual copper and glass seal combines the center electrode and insulator together for a gas-tight seal.

Improve throttle response: this spark plug fires leaner mixtures than conventional plugs and improves throttle response. Ensure reliability: the denso standard u-Groove Spark Plug is 100 percent pre-fired to ensure reliable operation and lasts twice as long as conventional plugs.

Greater spark energy means improved flame travel, and efficient combustion. Choose consistent combustion: the denso standard u-groove spark Plug employs a unique, producing more complete, consistent, channeled ground electrode designed to generate a larger spark nucleus at the point of ignition.
