The patented DENSO Iridium TT Spark Plug is fast becoming the standard for modern high-tech engines. YES Auto Parts stands for value, selection, and quality. Add details likeI tried to install this part, and it didn't fit.
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..
