Review on 🔥 E3 Spark Plugs E3.36 Powersports Spark Plug | Enhanced Performance Plug (1) - E336 by Corey Holloway

I installed these E3 plugs a few months ago and was initially impressed by the smooth-running power of my 88ci Twin Cam. t starts correctly. Pulled spark plugs and they look fine, but something was definitely wrong. I got a set of NGK Iridium spark plugs from my local parts store and had them replaced in the parking lot. Cylinder failures are gone. As I suspected, the rear E3 spark plug was malfunctioning. And after only 2500 miles it was extremely disappointing! Save yourself all the hassle off the beaten track by using those crappy E3 connectors, just use NGK Iridium connectors to get started!
