How often do u need 2 change the Spark Plugs....
What year, type, engine and truck???
G.M. said they are good for 100,000 miles.....but you can put in new ones before.......I changed my out at 80,000 miles.....
The Vortec engines run Better....with A/C Delco plugs......Of the A/C Delco plugs,you would want to get the A/C Delco Iridium Spark Plugs,also.....take a look at the plugs wires....and there you could go with A/C Delco or Aftermarket wires.
I also have a '05 with 5.3. I changed mine at 80,000 miles. They looked good and most likely would have gone 100,000 miles,but I had them out so I changed them and saved the old ones for a emergency. As 99'Heartbeat said go with A/C Delco Iridiums. You can get them at AutoZone stores.
Also, I let my truck sit overnight to let the aluminum heads get cool, to help keep from striping the heads. Use anti-seize on the new plugs and torque to speck.
whats the gap on the spark plugs for a 2003 silverado 4.8 v8
cuz where it shows that info on my truck got a blurry so i dont know
For your 4.8 liter....The Gap for the.....A/C Delco Iridium Spark plugs is....0.40......they are already Gaped right out of the Box,from the factory.
How much does autozone want for the AC Delco plugs? I found them on Summit Racing for $6.95 a piece. They recommend Loctite Copper Anti-Seize Stick and a Taylor Spark Plug Boot Removal Tool, is the boot removal tool really needed? And is there a special tool to make sure you tighten them to spec?
