Cured my spark blowout issue

I was having some spark blowout issues with a set of NGK TR6's. I installed these plugs while increasing the boost even further, and they've been excellent.

    Motorcraft spark plugs

    October 03, 2011

    Great plugs, and one of the best prices I found. One of the few installs on a Cobra that is actually easier to do than on a GT. Gave it 5 stars all around because because its the best product in my opinion for a stock Cobra.

    Made the miss go away

    November 10, 2009

    My 04 SVT Cobra had a slight miss and a surge at idle speeds. I had tried NGKtr6 plugs and they ran ruff so i upgraded top NGK tr7 IX and that fixed the problem for about 5K miles then it came back. I wanted a new plug and was pointed to these. This did the trick. miss and surge have gone away. I also cleaned the maf and IAC just to be sure it wasnt them that was causing it.
