Where did you find that one? I goggled it, and it is a 2.0L I6 engine used with less compression and power than the 7M-GE. Wikipedia did say some Supras used it. Wow
. I doubt the 7M-GE plugs would work. The heat ranges must be different.
I located a Toyota spark plug chart, and the 1G-GE engine uses the same BPR6EY-11 plugs the 1988-1992 Corolla with the 1.3L 2E engine uses. Here's the chart.
