Ngk V Power Spark Plug Ur4 (8 Pack) For Gmc K3500 1979-1980 7.4L/454

Ngk V-Power Spark Plugs Offer Economical Performance For Nearly Any Automotive Application-And They’Re The Only Plugs With Ngk’S V-Groove Technology. These Plugs Enhance Ignitability, Lower The Voltage Requirements Of Ignition Systems, And Have Strong Characteristics To Prevent Fouled Plugs, While Improving Fuel Mileage And Acceleration Performance. The V-Power Plugs Are Also Highly Durable Against Electrical And Chemical Wear, Making Them Long-Life Replacement Plugs. Because Of The V-Groove, The Spark Occurs At The Edge Of The Center Electrode-So Heat Is Not Absorbed By The Electrode Itself. This Allows The Flame Kernel To Expand Quickly And Efficiently For A Complete Burn And Great Performance.
