As all the gap adjustment tools didn't work for me, i created this tool for my spark plugs.

These will fit the BPXXX NGK spark plugs, all EVO, DSM (maybe other Mitsubishi cars also use them) will work, including the standard BPRXES or EVO 9 longer plugs, they are M14x1.25 plugs

You can simply use an M6 bolt and M6 Hex nut and it should work, either glue the parts or leave them as it is, still works.

Just leaving this here for the few people that will find it usefull :)

Enjoy!
