These are NOT the OEM wires.

These are NOT the OEM product!
ACDelco has two lines of ignition wires.
748HH (no 9 in front of part number) is OE product and is what is sold by dealerships and full line ACDelco distributors.
9748HH is ACDelco **AFTERMARKET**, built by another manufacturer, licensed with the ACDelco name.
I am aware ACDelco themselves does not make the 748HH OEM product, but do not be duped into thinking you are saving that much money compared to OE parts providers.
