Purchased six (6) of these Hitachi coil packs after talking with Dalton from CZP. I wanted to be certain that the coil boot to spark plug connection was included in the price for the coil and Dalton confirmed that it was. Hitachi is the original manufacturer for this coil. However, marketing permission is not allowed for them to advertise it as OEM Nissan parts. Great price for the combo of Boot and Coil pack. I restored my Z at 113,000 miles on the odometer back in 2009/2010. It now has 122,000
