I found this while on Denso's Website, it a new set of plugs they have. ... /03_1.html

Anyone knows which would be the proper application for the 4AGE ST

Hook, maybe you would have some insight...

Your standard NGK BKR6E (Denso K20PR) plug for 4A-GE 20V has a 19mm reach, these are all 26.5mm. That means 7.5mm more protrusion into the combustion cylinder...mighty close to your piston crown. If you REALLY want these "Iridium Tough" plugs, use the VK20.

Here, see this chart: ... 037_3.html
