I have used Ngk iridium spark plugs for the last ten years in my cars and they have performed faultlessly in all weather conditions, I have used most types of spark plugs and found these give me smoother driving and better acceleration combined with good fuel economy, long life and excellent quality. Worth paying a little extra for piece of mind and continued reliability.
