No and I wont. No need to. Spark plugs wont make any additional HP or TQ than you had with the new OEM stuff. The standard AC Delco IRIDIUMS are excellent plugs. Any iridium plug will work fine. Those plugs in a C6 cause CHARGING SYSTEM FAULTS. (No one knows why)
Anyway,, unless you need to prove that they work better or don't; be my guest. If they were that good, don't you think that SOME CAR MANUFACTURE, would run them in their engine as an effort to improve performance and efficiency???
Fancy spark plugs and spark plug wire hype does NOT make a C5 or C6 work any better than any set of new plugs and wires.

Another proven spark plug fact:
The best performance plug in a heavily modded C5 or C6 is a standard copper core plug. The problem with using them are,, they do not last longer than 15-20 thousand miles reliably.
The Iridium plugs will last 50-60k miles very reliably. Thats the only reason Auto Manufactures uses the fancy Iridium Plugs is for the ability to maintain emissions for the period required by the power train warranty. They flat work without any issues for a LONG time!

While testing more than a few ignition systems for my race car I noticed that no matter how many electodes a plug had,the spark only jumps from one point,never from more than one.So all those extra prongs are pointless.

What I would like to know is everyone says they run the NGK TR555's but aren't the standard AC delco copper plugs a lot better? I know your paying more but in my opinion the NGK's are just a cheap option. A lot of vendors sell you the NGK's when you supercharge your car and I don't understand what is wrong with the copper plugs or how the NGK's are better.
