I saw these on Fix my hog. Later at a hog event. Finally purchased them at Biketoberfest in Daytona. Wish I would have ordered them earlier. Such a difference in stop and go traffic. Florida keys traffic is insane at times. Feels like a furnace moving at a crawl. Even with synthetic oils, this has to add to the wear. Cool – Master makes a huge difference in stop and go driving. Referrals your way and thanks again for saving my engine and my skin. – Donnie W, Key West, Florida
