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.

Besten Zündkerzen weltweit, keinerlei Startprobleme bzw. Fehlzündungen unter hohem Ladedruck mehr, weil diese Kerzen nicht mehr verrußen - eingesetzt sind diese Kerzen in einem Porsche 933 Turbo

設計時からトヨタ車はデンソー製前提ですからね。2835proタービンに変えてますが、消耗品として十分です。
