I had installed these plugs right when I got my first tune, and everything runs smooth with zero issues. Plugs are pre gapped to Hyundai spec so very simple install, completed in less than 10 mins.
Swapped these in when I installed my Scorcher on my Elantra GT N-Line. No problems, work great, no knock.
