Review on πŸ”₯ E3.34 Power Sports Spark Plug by E3 Spark Plugs - Top-Performing Spark Plug for Enhanced Engine Power by Napoleon Robbie

Revainrating 3 out of 5

Seems ok but! for parts

They look fine, but if you touch the threads you'll see they are rough carvings with flat points at the burr. These are not rolled precision threads. Raw flat parts must be obtained loose from factory containers. I had to cut the threads with a die to remove the dents and gap plating in the aluminum shovelheads. They were snug with fat to set them in. I'll see more about mileage performance later.
