NGK Iridium IX Spark Plugs BR8EIX #6747 - High Performance Spark Plugs for Motorcycles, ATVs & Small Engines - Improves Acceleration & Fuel Efficiency

I never used to believe that a spark plug could dramatically increase performance... until NOW!!! I bought the BR8EIX to replace the standard NGK plug thatI've been using in my 2001 Yamaha Blaster 200. The only hope that I had was that it would smooth out the rough idle that my four-wheeler has always had, but it did WAY more than that.Throttle response has dramatically increased, and acceleration is by far, much quicker.When I mash the throttle on my 2-Cycle now at mid-range it almost throws me off! And it sounds so much healthier.If you are using a standard platinum spark plug, but are skeptical to switch to an Iridium tip, don't be. SWITCH NOW, and have no regrets!
