Description of NGK 93911 LKR7AIX Iridium Spark

Designed specifically for the performance enthusiast, Iridium IX offers extreme ignitability, improved throttle response and superior anti fouling. The 0.6mm laser welded fine Iridium tip ensures high durability and a consistently stable spark and the tapered ground electrode minimizes electrical Quenching Effect. Longer insulator nose prevents fouling, the corrugated ribs on insulator prevents flashover, and a triple gasket seal eliminates combustion gas leakage. Iridium alloy has extremely high melting point, giving it high durability to heat and electrical wear, perfect for today's high-performance engines. Trivalent Metal Plating - superior anti-corrosion and anti-seizing properties.

Great fork! in ignition parts

Got 8 of these spark plugs for my 2008 Mercedes S550 4Matic. I immediately noticed an increase in acceleration. I've only had them a week so can't comment on mileage, cost or durability. But they were easy to install. I found the torque settings on the NGK website. You probably don't need an anti-seize coating on the connectors as they are designed to be used without an anti-seize coating. Note that torque settings may change when using anti-seize agents. Would buy this brand again.

Pros
  • Trivalent metal coating - excellent corrosion protection and extreme pressure properties
Cons
  • There are disadvantages
