In Korea middle part Daejun city area one of Church Protestant Mr. Chung,
he used Cyclone 3 unit- 2 intake, 1 exhaust,
one month later he fixed Plasmaplug for 1 year at his latest engine KIA Opirus V6 3.0.
At that time he recommended Plasma plug to other man owned Grandeur XG V6 3.0 also.
Because of much better in function than Platinum plug.
Lately I suggested free change of Plasma spark plug better designed,
initially he said this Plasma plug also very good and why?
Anyway he returned former ones.
12 unit of Plasma plugs photo shows with his memo-
new Plasma plug is better then former in power.
But in photo I found those plugs were not tight fixing enough,
all plug must fix tight, plug washer must be flat, for hot temperature must flows well
to engine block, otherwise engine happens knocking, so some part can be melting,
with power loss, more fuel consumed.
