spark plug gapping
I bought 4 Toyota Denso dual ground plugs for my Camry. I looked at them and the grounds are different distances from the electrode. I don't know how to gap them and need advice. thank you

The plug manufacturer is supposed to gap the plug to the cars engines specification. If you purchased the plug take it back for a replacement.
DIY setting the gap on these plugs is supposed to be a no, no. You can try to use a tool such as in the link below to bend the ground electrode and set the gap. On each side of the tool is are hooks that grabs the electrode to allow bending it. The hooks have different gaps to correspond to the different thicknesses of a electrode. The loops around the sides of the tool are different diameters of wires. To measure a gap, insert the different wire loops until one just clears the electrode gap and read the diameter on the tool. The internet has utube videos on how to do all of this.
