I'm not kidding, my car runs flawless at all times, unless I use the Denso Iridiums. After the makes 15Psi all I get is stutter, like if I were to try my NGKs gapped at .032. I've never used the Denso's gapped larger than .028. I have no idea how you could have no problems with yours, and I can't even get 60' down the block without sounding like my car has a stutterbox hooked up to it. My coil pack has never had any issues, and my plug wires are 3 months old. Not to mention, I've spent alot of time routing my plug wires and binding them together in a way that they could never arc out. Plus, I tried another set of lesser cost (NGKs instead of the Magnecors) with no change in results.
