    As some others have stated; Champions. My current set has about 4000 miles on them. I'm going to replace them before our big trip this year for the 'just because' factor. I had NGK before these Champions and I like the Champions, if no other reason than I can pick up the champions at any parts store, anywhere in the US (if needed - LOL). Bob - NE Ohio

    There's a dude on another forum that come in and talked about
    Autolite Spark Plugs.
    He said they have dynoed Harleys and got 2 hp better with Autolite Exreme Performance plugs. The number for my bike is XS4164
    I'm going to git a pair and try them.

    I saw the same post from that other guy however Dyno results can vary by even the humidity in the air so I wonder how accurate the results really are. A lot of others on that same forum posted that the stockers worked well for them, others said the autolite plugs seemed to last longer and the ones with the expensive plugs got no better results.

    I've been runnin Autolite 4164 Plugs.
    Seen the Champions foul out a lot in older bikes. We had the Champion plugs fouling out in a old sportster on a Hill Country run last year. All they had to go back in it was Champion too.
    Know when I used to run Dirt bikes and the champion plugs fouled out we used NGK and they lasted longer.
    Want to run a cleaner burnin plug like the Autolite extreme and see how they run compared to regular plugs. I think the XP Autolite plugs will produce a stronger spark.

    As I was sayin in a earler post I have 2 friends with Indy shops, and one is a MMI graduate that was #1 in his class in AZ, and they like Autolite plugs in Harleys I think I will stay with Autolite.
    Just cause HD runs Champion don't make them the best plugs. HD goes with the best deal they can git too.:gah:

    Probably kind of like Harley oil, the cheapest bidder wins. I'll have to try the Autolite plugs the next change.

    AutoLite 4265s have the best record in my S&S carbed '97 RoadKing...they actually made it to 10,500 miles in use. The HDs and Champions barely ever made it to 5,000 miles even with cleaning them every 1,500 to 2,000 miles ...

    I've got some NGK Iridium IX ( BPR5EIX-11, stock number 2115) in it now and they're doing fine at 4,500 miles - my parts store either didn't have or actually, I believe that they said that these were THE same as AutoLite Iridium plugs...do plug companies buy from and re-lable for one another ??? ... Anyway, I must say that I've not noticed any better running from the bike than the 4265s gave ... and at around $7 each, these will have to run at least 30,000 miles to be cost efficient!

    Was at the dealership last week and standing at the parts counter. Over heard a conversation between another guy and one of the parts guys about spark plugs. The HD parts guy was really pushing the SE plugs on this guy telling they are advanced over all other plugs, will lost longer than the stock plugs and will out perform all others. It was all I could do to keep from telling him, go buy an autolite plugs and save your money. I would have said something to him except the parts guy pulled him off to one side really working on him.
    they didn't what I wanted anyway so I left thinking that I'm sure glad I know about Bike Talk and the good info you can pick up now and then.
