Good package as it comes with 6 plugs; fits the truck and it’s now smoother. I’ve always used NGK where possible and this is bo different. Gas mileage is up slightly (these trucks are abit thirsty) but overall power delivery is smoother, more linear and alittle more low end grunt now. Tip: if you are changing the plug over on a 98 S10 4.3L then you will find that the driver’s side middle spark plug is hard to get to without first moving the steering shaft out of the way. Steering shaft has a long bolt that you need to loosen and remove to disconnect shaft from power steering box.
