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

I ran them on a 2004 Harley Screaming Eagle Electra Glide with a 103 engine. I felt a drop in power above 4000 rpm and knew my 2 year old spark plugs could be the problem. . These E3s are so cheap I bought a pair hoping for the best. Pulled the old spark plugs out and put the new ones in. The best part? No E3 breaks, just plug and play (sort of). I went for a test ride right away and I'm happy to say they made a great impression. No more power loss at high speeds. I've used them for about 500 kilometers and have no complaints. I can't say they perform any better than the new stock fork (you'll have to test them back-to-back on a dyno), but the fact that they shouldn't be overlooked is good enough for me.
