Spark Plugs & Spark Plug Wire Choice
I was wondering since I have to change my spark plugs as well as the wires what do you guys have and what are your recommendations for a V6 3.8L 1999 Camaro?

What about these wires would the combination of those spark plugs along with those wire would be good?

The factory used Iridium plugs that were made by NGK with the A/C Delco name on them as well. They are rated for 100K miles and when I pulled mine out at 131K they looked like they were about done but not overbaked. I could not afford $7 per plug so I got the next best thing which is double platinum. Good for 80-100K, and my brand preferance is Autolite.
Wires I didnt do anything special here I just picked up a set of BWD Select wires for my car and all has been good here. I have a stock engine and ignition system so I didnt need to spend the extra money on the performance wires. I recomend no matter what brand of wires you go with get a lifetime warranty, the quality on the wires seems to be signifigant to the 1 and 3 year wires.

OH and stay away from the Bosch Platinum +4 plugs. They are great in little high revving engines but not in 6 or 8 cyl, low revving high torque engines. I get alot of unhappy customers who buy those plugs for domestic engines.

Did you read the article?
"They are different designs--the ACD plug is platinum-tipped, the Denso uses an iridium tip and is, also, a colder heat range, better suited to an engine which runs hard."
The missing piece is, that the ACDelco plugs are NGK-made, so apply that to the above statement and other details of the article.
"Dyno runs, quarter mile testing and aggressive street driving made colder spark plugs desirable, so we installed Denso IT-20 Iridium Power plugs which are sold by THR. The IT-20 is one heat range colder and its iridium tip is more durable but has less resistance than the stock platinum, AC Delco plugs that were in the engine when we started. The Densos' small, 0.4-mm center electrode and tapered ground electrode give the spark maximum exposure to the incoming, air-fuel charge. We should add that even General Motors must see merit in the Denso spark plug design because after about 2004, some Chevrolets have Densos from the factory."
