This is a new ignition coil for a 749, 998, 999, S4R, S4RS that use coil over plug only. This will work on any testastretta engine of that generation that has coil plug at cylinder head. The updated part comes with a wire extension (part# 38010143A) you can no longer get this style any more. It is missing the package, but is brand new and ready to install. They retail for over 200.00 new and like I said they don't make them with the plug on the coil anymore.
