| run an m8x1.25 tap through and be done with it. Otherwise a ~$30 m8x1.25 helicoil kit available at any auto parts store should do the trick. I personally would not do the balance tube with the plenum installed for fear of shavings getting in the plenum. If its just the coil packs then it should be a breeze. Good luck.
