5-Year or 100,000 Mile Limited Warranty
E3 Automotive spark plugs used for personal, family or household purposes are warranted by the manufacturer to provide an experience of more power on less fuel, quicker starts and less fouling than competitive standard spark plugs, and to be free of defects in material or workmanship, for five years or 100,000 miles from the date of purchase. In the event of provable defect within the stated warranty period, the manufacturer will either replace the item(s), or refund the purchase price at their discretion

Iridium plugs are a requirement because the electrode wears much slower and the gap stays in spec much longer and they have the correct electrical resistance. NGK makes the AC Delco plugs that come from the factory. The NGK TR5IX is the OEM replacement. I wouldn't use anything else if you want your engine to run right and last a while. I use AC Delco wires because I know they have the correct resistance and there isn't much price difference when compared to after market.

If you use after market plugs or wires, be sure they conform strictly to OEM specs. Plugs or wires that cause too much resistance will still work but it causes your coils to work harder which will shorten their lifespan. Also, once your plugs start to wear, the gap will increase much quicker and the spark will be much weaker. This causes less efficient combustion which leads to more unburned fuel in the exhaust gases which will cause the engine to lean the mixture resulting in power loss and in some cases will cause your cats to burn hotter and eventually fail.

These exact circumstances happened to my first Tahoe at 150,000 miles. Replaced the cats at $400 each, and 3 weak coils at $90 each. The mechanic showed me the plugs he removed from the motor and they were way out of spec with only 10,000 miles on them.

I'll never use after market plugs or wires again.

For those of you running Taylor wires, how long are they?

I have an '03 yukon with the melco coils and need 10.5"+ long wires. Summit racing doesn't list the taylor wires for my truck but lists them for pretty much everything else.

Edit: I check taylor's website and the 53005 are 10" long. Not sure they'll fit the melco coils.

Two coupons worth mentioning for advance auto right now

Code - P20 - 20% off
Code - AP55 - 15% off + $50 next order of $100+

Use both of them at checkout and you will get 20% off order and the $50 coupon.

The coupon is only good for a little over a month, so buy everything you need now and then on your second order spend over $100 and use your coupon.

A quick comparo for my 5.7L OBS:

This site is REALLy easy to navigate for the parts needed for a Tune-up...check "Ignition & Tune-up" under the "Replacement Parts section"

Sparkplug wires are INSANELY expensive @ Advance, get them somewhere else.

I used all the AC Delco part numbers from Advance and plugged them into:
http://frugalmechanic.com

I'm personally going with Advance b/c if i split my order in two (using the $50 coupon), I'll come out ahead pretty significantly...minus the wires of course, those I'll get somewhere else.

Hope this helps!!

I've used OEM AC Delco plugs and wires exclusively for almost 5 years with nary a hiccup. Sure, they aren't the bling bling super-duper awesome hot sh*t plugs and wires that are the latest craze...but they work great, they are reliable, and theres no need to upgrade either item unless you're significantly modded and making lots of power. Besides, they last for ~100K miles (depending on the driver, of course). I'd rather do it once and be done with it for a while - the rear plugs can be a bit of a ***** on these things.

Speaking of which, I'm about to order a new set for the burb at 230K - I order most of my parts from www.rockauto.com. Great experiences with them. Wire sets are around $58, and plugs are around $5.50/ea there IIRC. They might be cheaper elsewhere but I'm ordering a ton of stuff from them all at once so I really don't care. By the way, here's a 5% coupon code for them: 51135383431335

Enter that number in the "how did you hear about us" block of the shopping cart and it will be applied when you check out. Saved me a fair chunk of change, about $40 off total (then again, it's a $900+ order). That number expires on May 15th though, so going if you want to use it.
