The platinum plugs are nice because they will last a long time and provide decent gas mileage. They will not really give you any more horsepower over standard spark plugs however so it all depends on how much you want to spend.

Ug... I use the motorcraft original platinum tipped plugs. They work fine, and last a long time.

My complaint on the bosh plugs is that the center electrode is too small, and wears out too quickly (around 15k in my experience).
Also when the center electrode wears down it recesses itself into the ceramic insulator, which eliminates a direct spark path from the electrode to the ground points.

Just my opinion.

I like NGK and I think that the stock double platinum motorcraft are good too.

I can't wait to install my Zex Hyperformance plugs, I am wondering how they will run when the nitrous is not being used, they should still be sufficient right?

Currently I am using Bosche Platinum +4's as well. But I've had them for about 2-3 years now so I think it's time for some new ones anyways.....
