This is in regard to a 2000 Chevrolet Silverado 1500 with the 4.8L engine.
The emissions label specifies a spark plug gap of .060, which seems kind of high, although the used spark plugs of unknown age and mileage have a much bigger gap than what is specified. They are Autolite AP5245.
I decided to go with NGK G-Power spark plugs, p/n TR5GP, which are offered on Rock Auto for this vehicle. These are fine-wire platinum spark plugs. I have used NGK G-Power spark plugs in my other vehicles, without adjusting them, however the difference between the pre-set gap of .034 and the recommended setting of .060 is large enough that I have to ask.
If you have ever used this type of spark plugs, did you adjust it, or just install as it comes?
