I was wondering if anyone out there has used Brisk silver plugs in there G2 Hemi. I have a 572 Hemi that I recently converted to EFI and would like to change out the Champion Racing C63CX non-projected tip, non resister race plug for something that will be friendlier on the sensitive electronics. Looking at Brisk's website, I think the DR14S would be the best alternative.

Any opinions or thoughts ?

I am running these in my efi Hemi:

I had a set of AR 3935 I installed today but they are more like a direct crossover from the Champion C63CX and are non-resister, Non projected tip.

I would not use a spark plug that i had never heard of before today, why would you?
I use the Autolite # 3934 race plugs in my 15.0 tp 1 compression bracket motor that I race on E85, E85 doesn't like the colder plugs like the 3933 or 3932
How much compression and type of fuel and octane are you trying to fire safely

Expensive plugs. Buy a set and try them. I doubt you'll notice any difference over a NGK plug. I use the NGK 6987 for all of the street build EFI engines. The 6987 is an OEM fitment for modern cars so it plays well with electronics and EFI and they only cost around $4 each.

The Brisk plugs are really popular among the modern performance EFI crowd and not exactly an unheard of plug, except for maybe the old muscle car community.....
The car is mostly street driven at this point and is a 11:1 compression pump gas engine.

On your deal I would use a Champion RN9YC or the smaller body RC9YC
Or the Autolite #3911 non resistor race plug or the resistor #3923
