I am doing a spark plug change tomorrow with the Brisk spark plugs and I was just wondering if anyone has used the Brisk (3VR17YS) spark plugs. If so, what did you set the spark plug gap at?

 

.040

 

.41

 

That's a huge difference....

 

Not as bad as the (dumb) current plugs .40-.50 variance.

 

.42 is the highest gap for that plug. Troyer performance recommends .40.

 

I just took a guess.. LOL

Won't make much difference on a N/A motor.

EDIT: LOL, .040 and .41 is a huge difference.!

 

I had Brisk's in mine, gapped at .35.

I am not a fan of that plug. Itook mine out after about 200-250 miles, and put in HT1's.

 

What was wrong with the Brisk plugs?

 

has anyone succesfully put these brisk plugs in a na f150

 

I had a really rough idle, not sure if it was caused by the plugs, the cops, or whatever. i didn't feel like going through each individual "cause", so I took the plugs out, put in the HT1's, the original cops, and it fixed the idle.
