Compre esta candela para utilizarla en mi carro a control remoto de 1/5 de escale MCD, la candela funcionó muy bien y tengo muy buena potencia y reacción del acelerador. La candela se ve muy bien hecha.

Good for Honda GX35 w/ proper gapping
With some proper gapping, this will run a GX35 engine just fine. Iridium powahhhh!

XTZ125に使用。NGK CR7HIXから交換。 開封して端子の形が違うんで一瞬焦った。「あぁ、バイクはコレ外すんだったわw」とすぐ気付いたが。 NGKも5万キロ近く使ったんで、新品同士の比較はさすがに覚えてなくて無理だけど・・・ やはり新しいプラグはイイ!ハイギア低回転で流してる時の安定感がまるで違う。燃費もスッゴイ向上。 ケチらずとっとと代えるべきですね。特にキャブ車はプラグも大事にしなきゃなぁと再認識。

Best plug to buy for any mode of transportation

Sin duda las bujias denso son de lo mejor que hay. Son incluso mejor que las ngk. Sobretodo las iridium power. Siempre las monto en mis vehiculos y el cambio es brutal.

NGKからDENSOに戻ったがどちらがいいとは言えず。もう少し使ってから再報告します。

新聞配達で使っているプレスカブ50に付けました。 さすがイリジウムプラグ、気温が氷点下に近く朝の2時台でも一発でかかります。 加速時も、低回転域からちゃんと伸びていく乗り味となりました。
