Spark Plugs
I've been hearing a lot about Iridium and Titanium spark plugs lately. Is there really any difference in what kind of spark plug material you use? Also, what brands are good out there? I might be replacing mine, they seem to be running a little weaker when I start.

Re: (Markov)
Iridium has a lower impedance, which is the opposition of current flow (lower impedance = less power needed to transfer the same charge) than titanium.
Frankly, I don't think you'll notice the difference, they are both excellent. These little details matter when you have a competition car, and every 0.001% performance gain matters.
I have NGK Iridium's in mine, just because they were available at the store I went to.
