From the ES page:

"NGK traditional plugs are constructed for longer life and optimum performance. Corrugated ribs prevent flashover. NGK uses only the purest alumina silicate in its ceramic insulator which give all NGK plugs greater strength and better heat transfer. Copper cored and triple sealed to further aid in heat removal and prevent interior leakage."

From the EGP page:

"NGK G-Power offers the performance and durability of platinum at a competitive price. The center electrode is fine wire platinum for better starts, superior acceleration and better fuel economy. Trapezoid cut ground electrode to reduce quenching."

From the PFR6H-10 page:

"NGK extreme life plug. By using the highest platinum content in the industry, NGK has created an extremely long life spark plug. Laser welded platinum tip on center electrode and platinum tip on the ground electrode. The center electrode is taper cut which aids in focusing the spark while reducing the voltage necessary to start the combustion process, this will provide better throttle response, improve efficiency and allow a smoother idle. Stainless steel washer reduces plug self-backing."

I don't actually mind changing plugs, so if the EGP's work as well (possibly with shorter life) for $16/set vs $90/set (price inflated due to local availability, this is Canada!), I might go that route next time around... but if it affects performance (I know these cars are sensitive to plugs), I'll stick with the expensive ones, at least until they disappear from the market...
