3. I can care less about what you run in your car or what you think works or not a guy was asking what people thought about grounds I told him what I had seen with my own eyes.
Like I said to start not all cars will respond the same to that mod(or and other) there all at diffrent stages of performance and mainteance. But I'm telling you grounds do help some cars.
4. I dont sell car part, I'm a jet mechanic I have no reason to hype up a product. I just call it like I see it.
5. I did mistype when I said more electrode I ment bigger. The smaller the electrode the more concentrated the potential at the electrode. Mine I believe are around 0.4mm.
6. Since they fire faster they give a slight edge on acceleration and they have helped with gas consumtpion.


Dear lord. Please try and learn punctuation, grammar, and spelling. It's very hard to even try and make break points between the gibberish! It also does very little to add to the credibility of anything you type when it is done in such a manner.

1. Iridium plugs have a standard ground electrode. Denso iridiums have their U-groove standard ground electrode. Feel free to check out any of the manufacturer's websites for picture proof of that!
Standard ground equals standard wear regardless of center (lead) electrode tip composition. Standard ground electrodes on our "waste-fire" ignition system are prone to extremely rapid wear. (I.E. Don't waste your money!)

2. Bullsh~t!!! 6 to 7 tenths of a second! The entire firing sequence lasts 1.5-1.6 mS. Wow. I am nearly dumbfounded at that response.

You do realize that 6000 rpm is 1 rotation every 10 mS
In case you are missing the entire point a millisecond is one one-thousandth of a second (1/1000)
Even a 600 rpm idle is 1 rotation every tenth of a second!

So you just stated these plugs fire 7 full rotations early at a 600 rpm idle!

3. That's really just more gibberish. If something doesn't work it doesn't work. (or more properly put doesn't help) Plain & simple. Just because you don't believe some body or hard data will not magically make it work.
If a car (like any made in the last decade or more) has a good series of grounds then adding more grounds is not going to accomplish anything but add pretty looking wires to the engine bay. "Bling, Bling!"

Yes the exact same theory applies to spark plug wires as well. The Magnecores I installed added zero performance over the fine set of stock wires, but they do look pretty and will last much longer.

Wires, grounds, plugs, etc will never generate extra power. However bad ones can rob power.

4. Irrelevant, scary to think about that considering your posts! , your call is dead wrong and you need glasses. (there's my uncalled for tactlessness you've all been waiting for )

5. In a way that is correct, but both PA and I have already well discussed electrode design theory previously. (See the part about lower emissions and better throttle response)

6. Wrong. Go back to answer #1. Though like previous stated in previous posts (and answer 4) finer electrodes can be better.
However they also wear out a lot faster. Two sides to every coin so-to-speak.
