Carmen,

Party was cancelled, wife baby sat all day with 2 grandchildren, way to tired for a party! Otherwise I was back early enough!

 

In all seriousness, what do you guys think of the new Denso or NGK Iridium plugs? I've heard nothing but good things about them. I've heard bad things about the Bosch Platinum +4's, but nothing but good about especially the Denso's.

The SVT Lightning guys absolutely rave about them and they really seem to help in the case of the Lightning, especially for those guys running a SC overdrive pulley.

 

I have also heard some bad things about the Bosch +4s. I don't know much about the Denso or NGKs, but from what I have read on this site, there's not much use to changing plugs on an S2000 unless you're going FI.

 

If you take an S that is in good operating condition and put in densos or other iridiums, they will make no difference. An iridium plug will shine under severe conditions such as in a engine running high boost and compression. I know cause i ran them in my supra which ran over 20 psi. They can withstand the harsh conditions and help the engine run smoother.
