    • Q:

      I have seen mixed reviews using pulstar spark plugs. Some say work great others had problems with burning out electronics or causing engine damage. Would these plugs be safe to use on my 1989 chevy suburban 5.7 V8?

        Pulstar recommends setting gap to OEM specifications for your vehicle. Up to 12% more horsepower and torque allows for higher towing capacity and overall power. Built-in capacitor element stores and delivers a much more powerful spark, providing for more complete combustion. Better throttle response, quicker ignition and improved cold starts. Yes, this Pulstar Iridium Pulse Plug with part#CB1I fits your 1989 Chevrolet Suburban.
