Brisk Plugs

[Fast Ford]

Anyone know the difference between Brisk GR12S and GR12YS spark plugs? I've seen both of these part #'s for GT500's running more than stock boost.

I used to run Brisk Silver plugs in my supercharged F-150. The Y should be a code for a projected tip.

The correct plug for your use is GR12 or 14 YS. Please refer to Spark Plugs 101 on the VMP Garage at vmpperformance.com for more.

Good info. Can you directly post it in a thread here?

Any recommendation on if a non-projected tip is better?
I run a NON-projected tip BRE7F and planned to keep it despite the change of E85 and more power (850-900rwhp).
These 4V chambers might influence this but I've never seen a discussion other than recommending the preferred plug of the tuner.
