I know how crazy this sounds but when I looked online for HD 6r12 plug I got a bunch of conversion sites. Went looking for Champion RA8HC and got 810 some of these are for lawnmover. I will admit I have not looked on Harley-davidson site yet. Would never have guessed it would be this hard. They a spark plug or am I missing something here.

 

i'm not exactly sure what you're asking here. are you looking for an alternative to the hd plugs, or where to buy hd plugs from?

personally, they're cheap enough that I go ahead and buy them from the dealer. they don't have to be replaced for something like 25000 miles. and with the newer bikes, the resistance of the spark plug is used for the knock resistor in the ecm. if it's out of spec, it won't work. does that mean the aftermarket plug is out of spec? I dunno. but why take that chance?

 

get them pulse star plugs!1 they give you 72% more horsepower, and 36% better gas mileage, and never have to be changed again!! They only cost 2.00 each, too!

 

Where?

 

I sell them!!! I'll tell you anything to get you to buy them!










In all fairness to you, this has been a long standing joke around here, Sorry I misled you. Honestly the dealer plugs are perfectly good to use, and you can't go wrong, or any better, really.

 

Go to any Advance Auto,I bought NGK's there.

 

Thanks Dealer it is. I asked what guys were carrying in there tool bags, plugs come up more than anything else.

 

You seem like a nice gut but that's a crock. Plain old Champion plugs do just fine.

 

I'm not trying to propagate any side here but I have read article after article that states there isn't any measurable difference between the Champion and the "high performance" more costly ones.


I don't know because I have never done a study about it, but that is what I have read several times.

 

See! new around here!!! and already starting trouble!!!!
