not really a horsepower adder, it will help your car respond quicker and increase efficiency.

While we're on the plug topic, does anyone know what the Iridium plugs are like, and are they worth the extra cash?

if your spark plugs didnt burn all the fuel.. then it would clog your cat and kill your engine. you shouldnt need a better spark then stock until your running very high horsepower.

They're not worth the extra money over the +2s.
