I just did mine with AC Delco Professional Iridium plugs. There is also a rebate on them right now

Rebate where?

Rebate where?

Its from GM, but if you go look up the plugs on RockAuto there will be a link to the rebate info. (https://www.rockauto.com/lang/en/promoCat.html#acdelcoPlugs)

I got $24 back on mine, which made them like $3 each.

Denso wires or GM?

I used the AC Delco wires as well.

Wire preference?

 

[Doubeleive]

ac delco, just think they went 112k, no reason a new set wouldn't go another 112k right?

 

[HiHoeSilver]

Wire preference?

I would go Delco unless you are gonna do something cool like a Taylor 10mm.

Any benefit to running Taylor 10mm wires?

Any benefit to running Taylor 10mm wires?

Less resistance, better conductivity = stronger spark with higher efficiency.
Maybe a little smoother idle or slight milage advantage. Better quality, longer life, etc.

Oh yeah... cool factor.

So..... not really. Lol. Just do it!

+1 more vote for stock AC Delco plugs. I'd also recommend stock AC Delco wires but if any aftermarket, I'd +1 vote for Taylor. I've had problems with MSD and Accel and I know I've read of others having some issues. I used to find Taylors for cheaper than AC Delco and they're available in cooler colors, if you're into that sort of thing.

Thanks!

Where did you find Taylor’s? Now I’m interested

I've only used the ones for the Gen3 and Gen4, but I get 'em from Amazon, Summit Racing, Jegs, eBay...

Here's a page from Taylor's application guide:

Called Taylor,
The only thing he said that bothers me was,
The heat shield around the plug will not fit over their plug boot.

Meh. I'd get heat socks. Those shields are just an OEM version of them. The socks work better, anyway.

Out of curiosity was a induction service ever performed on your Tahoe?

You’re not going to notice anything with pricey wires and plugs. Go OEM for both and call it a day.

Rebate might still be going on for the plugs, I ordered them and wires from Amazon and plugs ended up $3 each after rebate. Don’t overthink this one.
