As title mentions. I've currently got NGK iridiums in my car and have had them for about 6 months, however when I swapped out my old plugs (just plain janes) It felt as though my acceleration and gas mileage kind of pooped out a bit. Acceleration not much, but noticeable as I drive it daily. Perhaps I was day dreaming, but whats your take on iridium plugs.

I've had very good luck with the Denso Iridium plugs...we picked up a little power on the dyno with them.

I recently read a report on these. They won't make you horsepower, just keep you from losing it when used in engines with extreme things going on inside the combustion chambers just as a supercharger. Other than that they are a waste of cash.

Realmongo, similar to what we have seen on the dyno, they seem to burn better with the extreme cylinder pressure we are seeing.

On a NA car I like reg Autolites or the AR series Autolites.
