I bought this for my 92 Integra. my original wasn’t completely shot but decided to change it anyways. the price was a lot cheaper than the parts stores. works great and definitely starts up a lot fast now.

The car has started every time, since I put this new EFI ( Ignition Fuel Injection ) main relay on !!!

冬に燃料ポンプの作動が悪いようで、エンジン始動できませんでした。交換で復帰です。パーツとしては、トゥデイ 用ではなくシビックEGなどで使われていたもので、ステーが上下逆です。その為、リレーのケースかステーの付け替えが必要です。私は繋げたまま放置してますけど、問題はないです。

古い部品でもここで見つかって良かったです。

絶版だと思われたメインリレーですが、EFシビック用の商品が新品で出ていてスターのみ入れ替えれば使用できました。現在のところ好調です。

30年物の車に乗っているので、部品を手に入れるのも一苦労ですが、まだ買う事が出来て修理が可能になるのもありがたいです。半信半疑で交換しましたが、ちゃんと作動してまた元気よく走るようになったので良かった。ちなみに車種はトゥデイです。

予備部品として購入。未だに未使用。将来への備えとしては高くない買い物。
