Independently Tested E3 Spark Plug Shoot Out!

[Raging64]

I'm usually very skeptical about new products, everything I do is on a shoe string budget and I stretch every penny. It has taken 3 years to save to build this engine. Our goal in to go 161 MPH for a record of Realstreet class at the ECTA. These E3 gave us an honest 12 HP, best money I've spent $ per HP. I have them in my daily driver as well. Oh BTW the stock GM 350 engine averaged 16 MPG on the highway in this car, our new engine averaged 18 MPG on the highway and it's 20 CI bigger. E3 4 Life!

@Raging64 Ive heard the E3 plugs foul out in 5-10k miles have you had any problems with them?

@NateWrabel I've only had them in this engine for 1500 miles, but I have 25K on them in my 93 K-1500 GMC.
