I had Bosch Platnum and Taylor 8.5s in my Camaro. Prob do the same in the yukon soon.

Why do you recommend the TR55s over others...they're on the expensive side and I'm just wondering what the benefit is; not trying to be difficult

Is there any benefit to getting expensive wires like MSD or just stick with ACDelco?

 

[slocaddy]

benefit to msd's is you can bend the boot (headers) otherwise stock is probably just fine and cheaper

ac iridium 41-110 is the oem plug.. the 5.3 seems to like the oem plugs

I havent splurged yet but get wires from these guys
http://www.firecore50.com/ I think they run $105/set for the ls engines


all I've heard is raves over these on the smoother idle and just smooth rpm's throughout the power band. From mild street cars to 1000hp race motors guys are bragging about them.
here's a thread on them

as for plugs, I'm like NGK's or a factory ac delco replacement

I had some Taylor 10.4mm wires on my 08 Sierra's 5.3L. Looks bad ass cause you could almost jump start a car with em! haha

Stock. No need for upgrading unless you go boost or nitrous, or a head/cam package good for 7,000rpm.

Having accumulated millions of miles on my fleet trucks, my experience is that for longevity the stock plugs and wires are best. I've tried them all and there is no difference in performance on a mildly modded engine and, FWIW, the stock plugs looked much better with high mileage (electrode and all didn't have as much erosion) AND they were easier to break free when time to change. These are aluminum heads, having a plug seize and strip threads will really ruin your day.

Just my $.02.

Denso Iridium 9's

 

[fire730]

I was just about to start searching for a post about this. I really dont have any mods yet so I guess I will be getting some Delco wires and AC Iridium plugs.

 

[TailHook]

I run OE - AC Delco Iridium 41-110 and AC Delco 9748HH wireset...

...wasn't planning on doing the wireset, but due to the abundance of space [sarcasm, the 6.0 has even less space than the 5.3], a couple wires were destroyed...my favorite being the passenger rear.

Definitely recommend anti-sieze on the plugs...as Jay mentioned. I also used some dielectric grease this time...we'll see whether it's worth it next change out.

NGK TR6 4177 gapped to .035 with msd wires, you don't need fancy $20 plugs for these trucks when a $2 ngk supports 700whp.

 

[TWITCH101]

what is the difference in the tr55s and the tr51s.....shop gave me the tr51s as a replacement....

[TheYuk]

ac delco iridium or denso iridium, Denso makes ac's. and ac delco or delphi wires

 

[creekdaze]

I used the 41-985 as opposed to the 41-110. They are both AC Delco, cost the same and are Iridium plugs. Does anyone know the difference?

41-110 is the new part# for 41-985, same plugs.

Anybody know the spot to get the best deal on these plugs and wires
