Twin Power 85-99 Big Twin 85-03 XL Exc EFI Twin Power Ignition Coil Black Replaces H-D 31614-83A

This is a Twin Power ignition coil, designed to replace the stock unit on a wide range of Harley-Davidson motorcycles, including Big Twin models from 1985-1999 and XL models from 1985-2003 (excluding EFI). If your bike is experiencing weak spark or starting issues, a new ignition coil can make a big difference. This coil is built with a durable, molded-epoxy construction inside a case that looks like the original equipment, ensuring it fits right without modification.

Compared to the stock coil, this Twin Power unit offers at least 20% more voltage. That means a stronger spark, which helps with easier starting, especially in cooler weather, and can prevent misfires at higher speeds. It’s a well-built part that aims to improve your bike's overall performance and reliability. It comes in a clean black finish that blends in well with most engine setups.
