    spark plugs for modified 2.2

    I'm getting ready for my annual on my 911 and would like some comments on spark plugs. My engine is a 2.2 with E cams and S pistons & cylinders, and webers. The plugs currently in use are Bosch WR5 DC+. The car is for street use only, although I do occasionally run it over 7,000 an love it. Is the Bosch plug a good choice, or should I consider an NGK?

    Thanks in advance,

    Rob

    NGK BP7ES or BP8ES, so cheap you can replace them rather than clean them.
