Specs At A Glance

Good To Know

Q: Do I need to gap the spark plugs before installing? A: Many plugs come pre-gapped, but checking the gap against your engine spec before installation is a smart habit. A quick check prevents misfires and saves a second round of labor.

Q: How often should wires and plugs be replaced together? A: Replacing the wireset and plugs as a set keeps spark delivery even across all eight cylinders. Follow your owner's manual interval, and inspect sooner if you notice misfires or rough idle.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
