E3 SPARK PLG E336 Power Sports Spark Plug With Diamond Fire Technology

replaced the spark plug on my lawnmower as it wouldn't start and the other one was all clogged up. Fast and efficient shipping. Lawnmower started on next pull when i put this one in. Would buy again.

Llevo tiempo echandole el ojo a este producto y ahora que lo compre estoy más que satisfecho! No sé necesita ajustar el electrodo de la bujía, ya que es arco fijo, y además la calidad de los materiales es más que ideal, conseguí 2 para una Harley sportster forty eight y no me dió ningún problema, es totalmente compatible al recambio de la bujía original "6R12" solo tengan cuidado con el torque de instalación y listo!!

I typically change the plugs in my Harley every year. Just put these in (my second set). Probably could've left the ones i have. Still look brand new!!

I've been running these plugs in a 2013 street glide (stage 1) for almost 2 years exactly and put about 20K on them. The bike was progressing to hard starts, some decel popping and a bit rougher idle. I pulled the plugs and all was intact but there were no sharp edges left on any surface and the center electrodes were generally rounded at the edges. As a note I have also run boostane pro octane booster the entire time. That may or may not factor in to the wear. I remembered being pleased with these plugs when I first installed them so I purchased them again. Comparing the used to the new, it seems there may be some very minor manufacturing changes such as the extension of the center electrode from the plug body. That may be due to the wear on the used plugs, I'm not sure. Here's what really matters though; after installing the new plugs, it was a "wow" moment. The bike started immediately and with authority. I rode 35 miles to work this morning and there was zero decel popping and everything was more crisp. Rolling on the throttle was beyond better. I don't usually sing praises for a product or try to justify my purchase but simply installing these plugs really made a significant difference. As far as mileage and such I'm not sure but performance wise, these plugs deliver. For around 13 bucks every couple of years I will continue using these E3 plugs. I may even change them yearly because the performance is worth it to me.
