Review: هذا المنتج ممتاز ويستحق هذا السعر،👍 Review: エンジンチェックランプ点灯し故障診断機で調べたところP0420（触媒劣化）。 ググってみるとO2センサーの可能性も・・・O2センサーグラフ確認したとこと触媒っぽい。 O2センサー交換で直る可能性があるとの記事から、念のためO2センサー自力で交換。 反応が良くなったためか、チェックランプリセットしても1日で再点灯。（交換前は3日で再点灯） さらにググってみると、この商品が効果あるっぽい。 触媒交換は10万円くらいかかるらしいし、祈る気持ちで注入し説明書通りに走行実施。 2週間経過していますが再点灯無し。O2センサーグラフでも改善を確認。 ## Features - Increases power, performance, mileage and saves gas by not only cleaning the entire emissions & exhaust system, but the fuel system as well.
