Best Ignition Electrode Spark Electrode

NGK Iridium IX DCPR8EIX Spark Plugs for 2006-2016 Harley Davidson V-Rod (Pair)

The iridium electrode is 25% smaller than a platinum electrode, and it's just 1/4 the size of a conventional nickel electrode.
Ultra-small diameter center electrode reduces voltage requirement and extends ignition system life.
The ultimate in spark plug technology and performance from the industry leader.
New metal shell plating has enhanced anti corrosion qualities.

Solid state suppressor, with two-piece glass and brass seal, can help reduce radio frequency interference, regulates spark energy for long electrode life, and helps protect against high combustion pressures.
Pure copper core provides great heat transfer and helps maximize plug durability.
Platinum on center electrode enables superior spark characteristics and can reduce voltage requirements of the ignition system.
Ribless insulator helps optimize plug to boot seal.
Some ACDelco Gold parts may have formerly appeared as ACDelco Professional.

Iridium offers better engine idle stability and smoother performance.
Iridium allows for smaller, more efficient electrode designs for improved cold starting and quicker acceleration.
Iridium fine-wire electrode helps improve ignition of the fuel and burns away carbon deposits on the tip of the plug as they form, to help improve fuel economy.
One piece suppressor seal blocks radio frequencies that can affect vehicle electronics.
Suppressor seal meters spark energy for longer electrode life and seals against combustion leakage.

According to the material and type of spark plug, the recommended mileage is different..
