Any good for the LT 1 or just hype??

I did a quick search and didn't find anything.

Thanks

 

multiple electrodes are a marketing gimmick be it E3 or any other.

 

What he ^ said, and how do you gap it anyway? Those types of plugs generally block the spark from the fuel air mixture.

 

HP TV did a back to back dyno test looking into E3's claims. they *claimed* the only thing changed was the plugs and the E3's actually gained like 7hp if I remember correctly. but whos to say they didn't tweak w/ anything else, I'd like to see a compleatly independent test.. we should find a member on here who has a dyno to test their claims!

 

The way they get horsepower is by replacing older worn plugs with newer plugs, and I still doubt those e-3 plugs would work very well or else racers would use them, and as far as I know, no one does unless they were specifically being paid to. They don't even have that many heat ranges of them do they? If you look at their catalog, they have the same E3.52 plug cross referenced to Champion RJ7, RJ8, RJ10Y, RJ11Y, RJ12, J13Y, RJ14Y, RJ18Y, RJ20Y - The ignition system has way more to do with it than the plugs unless the plugs aren't right for the job.

 

The E3's are a little different than the other plugs that use multiple ground straps. In the "other" plugs, the the ground straps shield the center electrode, shrouding the spark and hurting the propagation of the spark. The E3's appear (I have never used them and have not even seen one up close) from the photos to place the ground straps to the side of the center electrode, putting the spark in a more "open" position. That is basically the selling point of the plugs. Whether it works or not is questionable.

A multi-electrode plug the shields the spark will hurt performance. A plug like the E3 with the spark coming off the side of the center electrode may be better than something like the Bosch +4, in that is doesn't hurt performance, compared to a single ground strap plug.

In extreme conditions (nitrous, forced induction), it isn't unusual for the standard single ground strap plugs to have the ground straps cut back to fire from the side of the center electrode, to unshroud the spark. So, the E3's appear to be headed in the right direction. But the only real advantage that they would offer over a single ground strap plug with the tip cut back, would be longer life, since as the gap widens on the strap that is firing, the next closest strap takes over.

All that said, I've never seen anyone use the E3's in a high performance engine. They always use a conventional, single strap plug, of the correct reach and heat range.

 

Besides what Kevin said about replacing old plugs with new, dynos are easily manipulated to make sponsors ad advertisers happy.

Saw a dyno test of a LT1 Impala with a Tornado. If you know what you are watching the operator held back on the first pull, then with the Tornado installed he let it rip and the car made what a STOCK Impala should make. Wonder how that happened.

 

DO NOT GET E3's!!!!!! I just put a set of these in a buddies 99 F150 4.2 V6 and 3 of the plugs were cracked out of the box. Also, we put 20 miles on the motor after the swap and one completely failed, no foul just stopped working. Replaced the bad one with one of the old plugs and the mis disappeared and the motor ran like glass. After dealing with these I will never go with a set myself.

Quality is crappy IMO!!!!
