Spark Plugs - NGK EGV model
EGV Types These plugs have a centre electrode of Gold Palladium Alloy. In addition, the insulator nose is an improved design to allow better gas flow around the firing end. The ground electrode is shorter and stronger, making the EGV range ideal for the most severe racing applications.

Spark Plugs - NGK iridium
NGK iridium plugs represent the ultimate evolution of spark plug technology and performance. The iridium center electrode is both stronger and harder than platinum. This allows NGK engineers to design an ultra-fine (0.6mm)center electrode reducing the voltage requirement for spark. This allows for a brighter, stronger spark from your existing ignition system. The ground electrode has a tapered cut at the firing end which reduces quenching for better flame core growth and increased ignitability. The combination of fine wire center electrode and tapered cut ground will increase performance, improve acceleration, and fuel efficiency.
