I'm looking for the best plugs I can get for my Dyna anyone any suggestions ?

 

Stick with OEM or equivalent. I got suckered in to the Pulstar plugs. Drop in MPG. It did start better when cold but thats it. Gave them to a friend and he didnt like them either.

 

Unless you're riding a nitro-fueled funny car, or dragster...NO.

 

Pulstar plugs are crap. I've been told that unless you have a highly modified engine the stock harley plugs are the best ones to use.

 

And the same goes for spark plug wires.

 

In a word 'no'

It has been proven many times over that no spark plug can improve performance or mileage. If you see a performance or mileage gain by installing a different spark plug, it is most likely because you 'accidentally' indexed it perfectly.

 

That too. Been there done that

 

Thanks for the info. Was wondering if anyone tried them in their Harleys.

 

I have them in mine. Bike runs great. Flame away

 

I know a lot of people think Plugs are Plugs, but I don't agree. You can clearly notice a difference in running NGK Iridium. As soon as you start the bike you can hear, feel & see the difference even when idling. In fact my idle increased on both bikes when I installed them. My Evo had a mid-range flat spot that's no longer there since the NGK plugs were installed. And I've seen mileage increase on both bikes as well. They're only about $15 per pair on eBay. For that price they're certainly worth a shot. They're all I'll run anymore, well worth the few extra bucks IMO.

Here's more info on these plugs if anybodys interested:
