Review on Denso 671 4081 Original Equipment Replacement by Dave Knain

Very poor quality compared to the original. Thin metal on the spark plug boots. They felt the latch and handle were not strong enough. Therefore, I checked the tightness of the connection with the spark plug, holding the plug in my hand. If you could make the wires click they would fall off and hang sideways or upside down. I'm sending mine back and getting a different manufacturer.
