Designed for durability under the most extreme conditions, DENSOs patented Iridium alloy is six times harder and eight times stronger than conventional Platinum making it possible to shrink the center electrode to 0. 7mm, dramatically improving ignitability

Will be returned as soon as I have a replacement.
When engine is cold starter works fine with engine is hot. It will free wheel the starter motor, but not kick the starter gear into the ring gear on the motor. Watch video and listen it actually did it twice at this location but I didn’t catch the first one on the video.
