I picked up a set of Brisk 3VR12S plugs for my Roush charged '04 Supercrew while at Troyers shop last week and installed them yesterday.
I had installed the second set of Autolites about 5000 miles ago (25,000 miles since blower install) and thought the truck was not running like it did right after the blower install.
These plugs have made all the difference in the world...Truck idles better, accelerates better, and when in boost seems to have a lot more b@lls. These are gapped at .032.Very happy with the outcome.
Suprisingly the Autolites came out very easily without any penetrants or cleaners being used.

 

I love my auto Lites, just need to be gaped properly!

 

I changed out to the Brisks last December or so, gapped at .032 also. No complaints, didn't notice a difference at the time, as I had to be gentle due to other issues (detonation).

I had NO issues with the Autolites, and you are correct that they must be gapped properly, which the ones I had in my truck were not. They were so clean when I took them out that I have regapped them to .032 and plan on keeping them as spares should I ever need to use them in the future. I wanted to try the Brisks and I like there one piece design.

 

[QUOTE=Marc Carpenter;3972360]i know exactly what you mean runs a world of a difference better. i took my plugs out. put new ones in, gaped to .032 and it runs great!
