NGK Spark Plug 7421; Standard BMR6A 14.000 mm 0.375 in. Flat

Details

• Increases both two and four-cycle engine power up to 12% over conventional spark plugs. More power helps get those big jobs finished faster.
• Reduce carbon deposits and material degradation inside your engine, extending engine life and promoting like-new performance.
• Patented Edge-to-Edge electrode design concentrates spark energy, resulting in easy starts in all conditions - hot or cold.
• Helps engines run more efficiently, burning fuel more completely. E3 equipped machines use as much as 13% less gas compared with standard spark plugs. Now you can work longer with fewer fill-ups.
• Reduce CO emissions up to 42% and Hydrocarbon emissions up to 58% in long term use as compared to standard spark plugs.
• The patented Diamond FIRE side wire is proven to increase power, reduce fuel consumption and improve hydrocarbon emissions in long-term use. The unique ground electrode and full-size center electrode also provides optimal performance for a guaranteed five years or 100,000 miles.
