Spark plugs, wires, cap and rotor help

[Brewcity]

Hey guys...a newbie here, and I need help with which spark plugs, wires, cap and rotor to go with. I have read through the forums, and have not gotten a real answer. My Tahoe has 84,000 miles on it, and I have read that going with a hotter plug of 5 rather than 4 will help reduce burning oil on higher mileage engines. Any truth this this?
I am just looking for the best set up for my Tahoe with my specific mileage.
Can someone point me in the right direction with part numbers please?
Thanks for the advice! I really appreciate it.

Thanks Jon....your always willing to help, and I really appreciate it.
Can I go with MSD wires (http://shop.advanceautoparts.com/we...MSD-Ignition_22360232-P_196_R|GRPTUNEAMS_____) instead of AC Delco? They are a bit cheaper at Advance.
Thanks again.
Take care!

What is the size of the AC Delco wires? Just curious? Are the MSD a better wire? They are a 8.5mm wire. Will this make a difference?
Thanks for the help.

msd are bigger and better delco are 7mm I think but every thing will be cheaper at Amazon. the difference will not be really anything you can "feel". But it is a step in the direction of ignition upgrades. In fact what you pay for Delco locally can get you msd products on Amazon.

Thanks a lot...will the MSD's need to be modified to fit, or will they hook right up with no issues of length?
Thanks again for the help.

you will need new wire clips from them as the wires are bigger.

I use wire ties, one large to bundle the 4 together and then 4 smaller ones to separate them, you can match the colors to the rest of your truck or you can use std black.

i usually go through summit for all my parts. always a safe choice since its local and its 1 day shipping to me.
MSD wires for me here with ac plugs
msd cap and rotor as well and the coil for a hotter spark


Never heard of a spark plug reducing burning of the oil, just the hotter the spark usually the better fuel economy besides in a supercharger/turbo setup..
