    Please tell me the proper AC Delco spark plug for my 2005 Tahoe gas engine. It has about 92K miles on it so i expect it is about time to change them????? Thanks for your help.

    :sign0016:to the Site......If you have the 4.8 or the 5.3 Liter,Then you would get the A/C Delco Iridium Plugs and they Should be Pre-gaped at 0.40,but Check to make sure.All so take a look at your Plug wire's.It may be time to replace them as well.

    For me its tough question to answer,you are in a better position as to how your Tahoe is running....I changed mine Plugs at around the same mileage you have on your ride,along with a New set of Plug wires.

    No problem with current pads. Still have some life in them but want to change before it is critical to do so. Any threads/pictures on how to do it on a 2005 Tahoe? Thanks again so much for your help.

    Where is the best place to buy the new plugs??

    On a early reply,summit has good prices or Local part houses...Auto zone etc.If you do a search at the top,there is may be a few threads on changing brake pads.
