Anyone purchase this item? It looks very robust which is good. There is a LOT more thread compared to the stock plug. I tried installing it on my engine, and the bolt seemed to run out of space with another 1 full turn left to completely seat. From this position, the bolt is easily loosened by hand (no tools required), which is a liability. I think the end of the bolt is hitting part of the lower crankcase. I will contact CMC to see what they have to say about it.
