Tune-up

[bikerglasses]

Looking for suggestions on spark plugs and wires --what's recommended? Any part #'s and sites would be helpful too. I have a 02 Tahoe with 105k on it which I just bought and would like to do a tune-up since one hasn't be done.


Thanks,
Ian

For our trucks, oem is probably best. AC delco iridium or NGK plugs and wires. You can get them at local auto parts store, ebay, or gmpartsdirect.com. Plug # 41-110, wires # 748gg or 748hh.
Here's a quote from Scottyboy- "Delco, Denso, or NGK are all fine as long as you get the Iridium plugs. All three were also used as OEM plugs. I bought my Delco plugs from Advance autoparts. I ordered them online with a 35% off discount code and picked them up in the store within 30 minutes. I saved over 20 bucks by doing that."

I am doing Delco OEM iridium plugs this week. I pulled my plugs to check and they are so toasted. No wider start up it so rough!

Is it pretty easy to change plugs and wires? anything to look out for or be careful with?

Pretty straight forward. Sometimes the boot rips off of the plug and might have to grab them with pliers. Most difficult part may be getting to the rear passenger side plug. This is were a universal extension comes in handy.
