My Yamaha VXR ski runs like new again! I had a misfire and my speed was limited to 40mph. A simple plug swap and I’m back in action.

商品自体はNGKですし，全く問題ありません。星は５点です。しかし・・・ 到着までに10日かかりました。 日本国内，本土です。カートに入れるときには，「アマゾンが発送 3日で到着」だったのですが，最終の代金の支払いのボタンの時には，いきなり２週間以上先の日付になっており，いつものようにボタンを押したときには，「時すでに遅し」でした。アマゾンのシステムの問題だと思いますが，急ぎの部品調達の際には注意です。

I replaced the plugs in my Yamaha 212x jet boat with these. I didn't have to gap them. They were already set for the engines. These are the same that came out of the engine. After 3 years of owning the boat with 100 hours on the engines I thought I would change the plugs, although the plugs were still working perfectly. So I know they will last at least 3 seasons.

NGKのスパークプラグLFR6Aを、YAMAHAのPWC(13’FX-HO)用に4本購入しました。近所ではギャップ1.1ミリ品はありましたが、0.8、0.9mm品が手に入らなかったので、Amazonさんで購入しました。まだ交換していませんが、休日に交換したいと思っています。
