I have never used them.
If there is any gain I would think it would be lost at $70 for a pair of plugs.
I used the oem 6R12's and swap them out once a year for about $3.50 ea.
They work just fine.

 

I use a $3 champion plug as good. Advertising!

 

This has been addressed many times in previous posts. Lots of opinions, most negative, I have them and I like the difference they have made in the way the bike starts, and throttle responce. Just my opinion. Be prepared for the nay sayers. if ya got $38.00 to spend I say give them a shot and decide for yourself.

 

I'm gonna give em a shot

 

Ask yourself one question before you spend the money. What are you trying to get out of those plugs? Fuel economy? Performance? What is your expectation?

 

Well I'd really like to boost my gas mileage with out tuning it but im sure its not gonna much compared to some other options and im not really worried about it starting better cold, cause it does fine now, other then that i would just like to see if it will give me better throttle response like they say, it would just be a plus

 

Both me and my dad have used them. Neither of us had any difference in fuel economy, neither of our bikes started easier and neither of us had a difference in performance. I changed mine out after a few thousand miles and the electrodes were rusty. That didn't happen with the plugs prior to and after the pulstars.

 

Just dip a pair of NGK's in gold and install them in your bike...will perform the same and possibly save you a few pennies...

Seriously, plugs are plugs and if you're looking for MPG's - get bike tuned, or install your own tuner.

 

You guys serious look at there dyno sheet from there inhouse testing i thinking going dual plug heads with these bad boy's
