Plugs are garbage. You can’t put suspect plugs in an engine. Especially expensive plugs in a really expensive engine. They were shipped in a brown envelope. All plug boxes were squished. All plugs were out there boxes. One plug fell out and is missing.

With the proper inserts I have been running these in my IO540-K1 aircraft engine for a year now. Haven't missed a beat.
