Some listed applications include notes such as vertical distributor towers or coil outside distributor, so confirm the original layout on the vehicle before ordering. Because this coil does not use an external resistor and does not include a mounting bracket, reuse the existing mounting setup and wiring path as equipped on the vehicle.
