I installed a 5# lower and I still have the origonal sparkplugs. I was wondering if NGK BR7's with .37 gap would be fine or should i gap it different? I have looked at a chart and it says .36-.38. Should i go with the biggest gap, the smaller gap, or the in the middle?
Also im getting some detonation at WOT in the final gear. Will the new plugs help this.

 

hey pete what's up? when are the CS L's gonna race? later

 

Whenever they're ready!
