How are you gapping them? > The iridium center electrode is very thin. Unlike a conventional plug, you cannot gap the plug by sandwiching a gap tool between the electrode and the ground strap, then pushing on the ground strap. The hard electrode will dig into the gap tool, and when you remove the gap tool, you’ll break the electrode. Instead, adjust the ground strap by tapping it on a hard surface, or by pulling it gently with a tool; then measure the gap using your gap tool. ---

^^ what he said. I started using NGK BPR7ES (fairly cold range for higher boost) or BPR6ES for moderate boost levels, and never looked back. ---
