When we first created the Dimple Drain Plug Magnet, we received comments and questions from many Harley Davidson owners who were wondering why they would need a Dimple product since Harley Davidsons are one of the few land vehicles that feature magnetic drain plugs (the aviation industry uses them almost exclusively).
So, we send one of our magnetic drain plugs and a stock Harley plug to an independent laboratory for research and comparison.
The results, speak for themselves. Our Dimple magnetic drain plug is 1,435 times as strong as the stock Harley plug. Check out the lab report yourself.
