NGK V-Power TR-55 Spark Plugs (.055 GAP) – GM LSx V8 Applications (Set of 8) – NGK-3951-8

NGK V-Power Spark Plugs -.055 GAP
Prior to 2005 GM used .055 GAP (this size)�spark plugs on all LSx motors. Starting in 2005, they switched to .040 GAP plugs�to provide a better idle�when things like cheap gas are�encountered. Either�a .060, or .040 GAP plug will work in any LSx motor with the smaller�GAP being best for daily driven, mildly�modded cars.�
