Hey All
Bought a set of Brisk plugs from Troyer and forgot to ask about gap.
'07 5.4l
Anyone who what it should be?
Thanks!

 

ask them. not many around here use them. They by design have a very short life expectancy. There really for supercharged engines..

 

Troyer said to use the smaller side of the stock gap spec and Brisk agreed. Brisk also said they can be re-gapped every 10-12k miles and can last 40-50k miles if done.
I can't believe how large the gap was on the stock plugs (100k)!!!!! Huge! Truck runs smoother and replaced my air filter. Can't wait to see what mpg's come to. I've been keeping track for about two and a half years.
One stock plug had the threads spinning on the plug so it must have been very close to breaking off. Other than that, no drama.
Thanks guys!
