What is the difference between colder spark plugs and regular ones? When you have colder plugs, after the car has bin running for a while does the car move more powerful. Not sure how to phrase that but I just changed my plugs and when I first drive the car it feels sluggish until I drive it for a min or so. I always warm my car before I start driving. But I have alot of work done to my car and a pre tuned ecu and it recommends the pfrb11s the colder plugs, and was wondering what the differences were, and pros and cons of each

Do you still have an NA? Colder plugs on an NA are of no use.
