What spark plugs do you use and why ( 2000 and newer silverado's and sieras )
Since replacing my factory plugs that came in the truck; I have been using the Bosch platinum 4's with the IR tip. The factory plugs where IR. I have never had any issues with the platinum 4's but there are so many other options out there, I want to know what you use and how you like them.
Also..... Spark plug wire sets.... There seems to be so many different grades (I guess when it comes to how much heat they will take) and the prices are all over the place. I usually replace the plugs and the wires at the same time.
What wires do you like and why?
