spark plug options...

hey guys, IIRC, the OEM spark plugs are good for about 100k km before changing them, and i know there is an optional spark plug which increases the performance a bit but has less running time before changing them....anyone know what is the performance model for the DENSO plugs?

OEM: FK20HBR11
performance: ?

I'm running Denso IKH20 on my F, i went with these plugs because i have run Denso IK serie on all my other cars. It gives me positive at good milage and smooth driving.
IHK20 has a U groove ground electrode that differ from the OEM plugs with 3 ground electrode. All other specs are both the same. Hope this help !
