Hi all,

has anyone experience with Brisk LGS Premium plugs on EVO? What what type do you use and are they better than stock?

Martin.

 

I've been using the HKS spark plugs one heat range colder on my car, just be sure to gap them to .022" or so for higher flow/boost situations. I don't have any experience with the Brisk plugs though.

Generally the stock plugs are fine up to around 400 crank HP, after that going one heat range colder is supposed to give you slightly better threshold for detonation. I think the stock plugs are likely already 1 step colder than typical cars from the factory and I've seen 500+ hp cars do just fine on them gapped appropriately.

 

I asked becouse I am running this car on liquid petroleum gas, which puts much more resisrence to spark creation than gasoline - and this is problem for platinum, irridium or yttrium spark plugs.

The Brisk LGS have silver central elecrode and all-around outer electrode, so that the spark can jump anywhere in 360 degrees.

I have ordered them and I will let you know my experience then.

I recently purchased and used the Brisk silvers and prefer the stock plugs more on my evo 10 GSR...switched back 2 days later but don't know if maybe I just gaped them incorrectly =/

Ams told me .028 since they built my car and is running over 27Psi on a Fp Red and a few other mods but it was breaking up hard when hitting boost. Called Perrin performance who actually sold them to me and said to try .020 -.022 and it worked much better but still wanted to switch back to stock and found the stock plugs make the pull much smoother. Also could have been the tune since it was tuned on stock plugs but im not expert just wanted to give my 2 cents =)

let me know how yours go

 

So I tried the Brisk Silver Racing BOR12YS recomended for EVO X. First I gapped them to 0,55mm and tried. In cruise worked pretty nice, with smooth idle. But under spool I could not get over 3500 rpm, the car started jumping and I got ASC failure.

I thought the gap could be too small and increased to 0,9mm. Thing went even worse...

I got back to stock plugs and feel sadness, as I used Brisks in all my previous non-turbo cars with great experience...
