Every one of our DRE custom Engine Diapers are made to your engine’s specifications. The “other guys” mass produce their diapers, which keeps the costs down, BUT they don’t fit very well. If you’re going to go to the effort to have a diaper on your engine, get one that fits like a suit, not a sleeping bag!
