Bosh Spark Plugs

Hi, just looking at the Bosch Spark Plugs for the 3.4l (FR8HPX) and have noticed that they are only single ground when the NGK BKR5EKB11 are twin ground. Sticker on the engine says use twin ground electrode plugs, so are the bosch ones okay to use or am I best sticking with the NGK at about twice the price? Car is on LPG if that makes a difference.

You must use the twin electrode plugs. But if you go for the Iridium ones, they are a quad electrode set up, which is better again.
