Anyone have any experiences with these? They sound like they are good but are they worth $13 a piece?

I would say YES. http://www.briskusa.com/

 

Hmm the source of the study is Brisk , so data could be slightly biased.

 

I thought that they made ice tea?

 

I'll buy those $100 spark plugs to go along with my msd coil packs lol.

 

they are good spark plugs
i have a set at the stock heat range
i cant use them with my nitrous setup
if you want then i can do it...50 bucks shipped

 

I've had these plugs in my car for a while now and overall I'm happy with them. My car had Denso's installed from the factory and with the switch to the Brisk I noticed the car became more consistent at the track. The other thing that I noticed is that I had to pull some timing out of the 4000-5.5,6000 range. I was showing 2-3* of KR. Pulling the timing did not have any impact on my et's whatsoever. I guess they burn more efficiently. Hope this helps! Oh yeah, I don't think I paid $13 a plug, I seem to remember paying under $90 for the set from a distributor listed on their site.
