Denso Iridium Spark Plugs is what my Mazdaspeed 6 demands when I want the car perform at its best! Fast start up, fast acceleration and responsive to throttle… the way an all wheel drive turbocharged vehicle should feel. Quality, Performance, and Value! 😎👍
Off the bat idle and low speed running is noticibly smoother and fuel consumption very slightly better. No major HP gains but car does feel more responsive..
