Pulstar!!! spark plug 12% horsepower and torque gain??

haha..

hahahahahaha

Bryson bro....hahahahahahahaha.....

So giving these plugs a run (the iridium). Noticeable difference after install and case learn (recommended by manufacturer for OBD 1 cars) So far immediate change in throttle responsiveness and it sounds more aggressive. As i run them longer ill update any other noticeable changes for those interested. So far seem entirely  worth the investment.

Recommend CASE learn after changing plugs? Thats a new one. I wonder if they are hoping you'll see a difference in performance. Glad you're seeing a return on your investment.

I won't claim 12% but the tech is sound, there was a sport import trick of placing condensers inline similar idea that worked

The good news is you can get these plugs for $10 apiece and they come with a lifetime warranty. I prefer to pull my plugs, examine, and replace about once a year, but to each their own.

Beyond that claim, I'm not buying any of their tech jargon. It just seems like a lot of hand-waving from a questionable authority.

Now, if you compared results before swapping plugs, then after, then again as before - you'd have my attention if there was any noticeable gain. You also want to test against a brand new set of your old brand plugs, as part of the "improvement" is just getting a fresh set of plugs.
