2003 Silverado 1500 with 4.3 ... looking for a good quality plug in the medium price range. Truck is used a couple times a week for light duty stuff. Wondering what you guys use in these engines ?
Well, that looks like the route I will have to take. I am dumbfounded that somebody doesn’t make a replacement for this part. I have a beautiful ‘03 low mileage Silverado that has developed a vacuum leak and this is the only spot I can find … the rubber part has pretty much perished. Very weird...
