    E3 spark plugs vs OEM

    I am looking at changing the plugs in my 96 roadster. Anyone use the E3 plugs and if so are they better/worst than the original ones? any input would be welcome..

    thanks....

    They have great marketing. Never used. I question how shrouding the spark with 2 additional grounding points improves things but I'm no expert on the subject. The tabs on the E3 seam to be oriented differently so that could be a benefit. I've always tried to make sure the grounding tab on the plug is away from the primary combustion area of the chamber but that is really old school stuff that may be more of a myth than real. Or maybe not. If you purchase, I would be interested in a followup with your findings.

    I had never heard of E3 plugs, so I did some searching. Couldn't find anything good said about them. All negative.

    More electrodes means nothing; only one spark will occur

    Splitfires all over again, proving silly fashion trends keep recycling.
