Straight from Carma Performance

Straight from Carma Performance, one of our authorized dealers, here is a back to back dyno. Carma just swapped a set of DR14YS's into a turbocharged Mazda Miata while it was on the dyno. It had NGK BKR7ES's in it before. This is a before and after with no changes other than spark plugs. The Brisk DR14YS produced right at 6hp over the NGK BKR7ES!

  • Brisk DR14YS's - 219.1whp
  • NGK BKR7ES's - 213.9whp
