    Spark plugs and color

    Hey Guys, just pulled my iridium plugs out of my 16 Vxr. It ran beautifully all year. Do these look a little the engines running a bit lean?(note: all 4 looked exactly like this) Should I run the stock plugs? Colder ones?

    Could simply be fuel additive.

    That's golden brown. Looks good to me

    White- lean
    Black- rich

    Golden brown- perfect

    Spark plugs and color

    Boostane , torco amongst other fuel additives will result in this color .

    Your plugs do not look lean at all! They look fine. The reddish color is either from an additive or just the way the camera took it. Lean plugs would be white.

    Dont mess with going colder. Just run stock. It’s not broke so don’t fix it.
