I had to settle for Bosch Super Plus with Yttrium (pero same heat range pa rin). Works well for me. Pero I will continue to look for a set of plugs which is a step colder.
My stock plug is K20HR-U11 (long reach plugs), local Denso distributor promised to deliver K22HR-U11 by next week, they say since there's a growing need for LPG users they will bring in these colder plugs.

Here's the contact info of local Denso. Look for Lito
