    Ngk br9es is the recomended plug. You can use br8es if your having trouble fouling plugs but be careful its a hotter plug and can lead to detonation.

    I run the NGK Iridium BR9EIX in my 02 Ultra. I do not think it makes much difference over the stock plug. It is more expensive. If your up on Ultra's you know the Pro's and Con's of Premixing. I did it and went back to oil injection. If your running the oil injection to the balancers on your Ultra you will be putting to much oil into #1 and #3 cylinder.
