Ranked #99 in Tools & Home Improvement · 1 things we like

Quick answer The KTC scores 8.4/10 with us. Amazon owners rate it 4.2 out of 5 across 18 reviews, below the 4.4 average of the 456 products we track in Tools & Home Improvement. It was listed at $94.19 on Amazon when we last checked in September 2026.

Combine the universal joint and oscillating extension bar with the plug wrench to greatly reduce plug replacement work for the Toyota 86 or Subaru BRZ. Can also be used on regular vehicles that use a 0.6 inch (14 mm) wide hexagonal plug. The dedicated case allows you to manage the tools you need.

Shape comparison: Adopts a shape that makes it easy to distinguish from deep sockets. Falling prevention: The magnet on the aperture prevents accidental plugs. Horizontal Opposition Engine: By combining universal joints and oscillating extension bars, inserting it while bending it allows it to approach the plug from a narrow space between the headcover and support frame on a horizontal oriented engine such as the Toyota 86/Subaru BRZ, which greatly reduces the working time.

    車両が歪んでるのかな？？

    プラグの場所によっては、そのままプラグの抜き差し出来ませんでした。が、一般的な工具で作業するよりは、かなりマシかな？と、思います。なんだかんだで、４時間近くかかりました。腰痛と格闘、コイルのケーブル固定ピンが飛んで、ジャッキアップしてアンダーカバー外したりしたので、そういったムダがなければ３時間以下で出来るかと思います。にしても、スペースなさすぎる。手が大きいので、無理やりねじ込んで作業してたら、手がパンパンに腫れました（笑）次回からは、工賃払っても、依頼しよーかな？て、迷います。

    作業効率アップ

    WRX S4 FA20DITでのプラグ交換で使用しました。エアクリ、バッテリー等最低限の部品を外せばレンチセット3点を繋いだ状態で取付、取外しができレンチの分割、繋ぎ換え等の作業が発生しない為、効率よく作業が出来ました。

    手持ち工具が少ない人向け

    フルサイズのツールキャビネットにしこたま工具を持ってる様な人であれば、手持ちのエクステンションの組み合わせ等で対応できるものの、使える組み合わせを想定して、あーでもないこーでもないと買い足していくのなら、コレを購入したほうが賢明。８６／ＢＲＺは意外とコイル・プラグのトラブルが多いので、長期的にみると結構出番はある筈。ただ、ちょっと高いかなぁ～

    機能は十分満足

    パッケージに取扱説明書が入っていないので ★四つ。 ネットで事前に見ていたので、大体分かったが・・・。機能的には十分満足しました。狭い隙間でスパークプラグの脱着が旨く出来ました。

    一回のみか？

    スバルのプラグ交換に使用。交換頻度が少ないだけに、また使うかどうかわからない(笑)
