Description

E3 Spark Plugs Spark Plug

• All new plug design features a unique electrode shape that maximizes the power created by the spark plug- diamond fire technology

• Electrode is a combination of performance and new technology that results in an improved flame kernel shape

• This flame front ignites the bulk air/fuel mixture faster, moves heat into the combustion chamber faster and creates a more localized pressure front for faster pressure rise during the cylinder power stroke

• The result is more complete combustion and an improvement in engine performance

• A truly premium performance plug

GOOD PARTS TO HAVE

5 by

great

3 by

Sent back; did not try them. Am not convinced the concept makes sense, and for the price, did not want to try.

5 by

great plugs !!!!

3 by

Bike seems to run hotter, louder, and more prone to blow off the slip-ons. I call that a marketing success.

5 by

Great Plugs. Started easier than the screamin eagles I had on there.

5 by

No gapping required, works great, nice spark.

4 by

I've had a set of these in one bike for 3 years now, they improved throttle response right way over stock ones and are still working fine. Was worried at first since they aren't USA made but they've proved themselves. I always keep backup plugs in my tool kit for emergencies anyway.

3 by

I find no real difference in this plug. I have used stock HD plug and screaming eagle and now the E3. all of them are the same. start,mileage,power best answer stay with the stock. brother has same scoot and performs the same as I do with the changes save money stay stock

0 by

You can get them for $5 at a parts and store made my bike run like crap don't waist your money.

5 by

These made my Road Glide purrrrrrrr... Seriously made a HUGE difference just on the idle compared to brand new HD plugs.

5 by

Replacement for original spark plug in my '06 Ultra. What can I say but 10,000 miles later and the bike runs great.

4 by

I'm giving 4 stars because only tome will tell if they are "the best" or not I only have a few hundred miles on them so far. My bike is a 2011 Softail. Does my bike run better? Well yes and no. I have not noticed any remarkable improvement on start-up but then my bike always starts easy anyway like within one engine revolution. So here is the stuff. Where I live we cannot always get good gas and motorcycles are restricted from expressways. I don't know if it is watered down or just low octane but some of the places we by gas here makes my bike run noticeably rough and loss of power with normal plugs but it runs smooth and has more power with bad gas with e3 plugs however I have not noticed any remarkable improvement when running good gas. So in my situation where I have to use bad gas about half of the time the e3 plugs do make a difference and are worth the extra money to me.

5 by

Have not had a chance to install, arrived on time, I'm sure they'll be fine. Thank you
