1992-1995 Chevrolet C2500 Suburban 5.7L V8. 1992-1995 Chevrolet C2500 Suburban 7.4L V8. GENUINE NGK SPARK PLUGS . Plugs feature a fine-wire Iridium center electrode and Nickel-alloy ground electrodes for maximum engine horsepower and torque.
I had a year ago installed AC Platinum v power plugs. I was a GM tech for 35 years. They failed,i was getting popping out the air cleaner and bad MPG.
I installed these NGK plugs and now my truck is running GREAT !!!!
I am a NGK guy from now on.
