Anyone Use E3 Spark plugs?
~Significant potential power increase: > 6% to 12% (depending on engine class)
~Significant potential fuel efficiency improvement: > 4% to 13% (depending on engine class)
~Drastic potential emissions reduction when used in 2 and 4-stroke engines (after 50 hours): 58% CO emissions reduction, 42% hydrocarbon reduction
Honestly I could care less about the emission reduction but anything that could free up more power and help me spend less time at the pump I am open to. I don't know if I buy into the whole thing about a spark plug giving more power but I suppose it's possible... Anyone have any experience with these? I know they ran them on Horsepower TV and claimed a gain.
Either stay with stock recommended or what some people including myself do is go to NGK TR-55's which is a great replacement plug for stock and mildly modded cars.
I'd stick with the tried and true NGK's for 95% of the street/strip cars on this forum!

Above is a thread where a tech from NGK posted a little feedback based on their testing of the E3 plugs!

E3's are a joke................so are all the other special plugs.
NGK TR55 or NGK TR5....gapped to .050......nothing can beat that for an N/A engine, whether bone stock or 650 RWHP. Nitrous/FI applications....takes different stuff and different gaps.
