did a search didn't see to much on those E3 plugs, I had tried them just for kicks (5.00 a pop), well they are horriblly manufactued , no quality control, gap is different on each one, ecletrode's are slanted, some beveled, some cross cut, and this was all in a selaed pack of four, Horrible! Can't comment on performance, but I would assume that these difference between each plug would greatly affect performace.

 

ya I bought em too but havent installed them. I wonder if the thier any good the saleman at Summit said they were new and good plugs. I wanted NGK but he talked me in too em and now im having second thoughts.

 

In general, "gimmick" plugs are just that.... gimmicks that offer little (if anything) in the way of performance improvement. In fact, multiple electrode plugs will still only produce a single spark, depending on which tip of the ground strap is closest to the center electrode. And, the multiple electrodes will probably shroud the spark and reduce its effectiveness. Use a high quality "conventional" plug.... copper or platinum, depending on your need to extend plug life and the use of a power adder.

 

You should return them if you can. Like Fred says, they are a gimmick plug and they have limited heat ranges and you cant set the gap - they do in fact block the spark from the fuel. I do R&D on different plugs and know the engineers at NGK and Champion - we see all kinds of these things which dont help the spark.

 

There ****, I can't say its cause of them but after installing, I've had the same plug wire fry 3 times, there 8.8 mm Accel w/ DYI heat protectors
