Product Details

Twin Power is known for well-built motorcycle parts, and this ignition coil is a great example of that. If you've got a 1999-2001 Harley-Davidson FLH model with EFI, this coil is built to replace your stock unit, specifically the H-D 31639-99 part number.

This ignition coil is constructed from durable, molded epoxy, housed in a case that looks like the original equipment. What's notable about this coil is that it puts out at least 20% more voltage than your stock one. That improved voltage can make a real difference, helping your bike start easier, especially when it's cold, and preventing those annoying misfires that can happen when you're really opening it up on the highway. You should also notice a general increase in how the bike runs.

This coil comes in a black finish and is designed as a direct fit, meaning it should install without any major modifications. It comes with a one-year manufacturer's warranty for peace of mind.
