Recently I put in NGK Iridiums based on feedback from most members here. If I had to go through it again, I would probably have purchased the NGK from the dealership at double the price.

The reason why is when I am at a stop I notice the car idles a bit differently. It doesn't really rev up and go down but it feels as it is going to. But when I am driving, I cannot complain...I do feel the power of the new plugs.
