Frequently Asked Questions

Will this ignition part fit my exact engine?
Match the year, make, and model where listed, then confirm engine displacement, cylinder count, ignition system, coil or distributor style, terminals, boots, and wire routing.

Should ignition wires be replaced one at a time?
Yes. Replace and route one wire at a time when possible so firing order is preserved. Keep each wire clear of hot exhaust parts, sharp edges, and moving components.

Do I need to change spark-plug gap after installation?
Use the gap specified for the engine, ignition system, boost level, and calibration. An ignition-wire or coil upgrade alone does not establish the correct plug gap.

Installation Instructions

Follow the current Granatelli Motor Sports and vehicle service instructions for part number 28-1573S. Compare every component, connection, dimension, and mounting point before disassembly. Use the correct tools, fasteners, torque values, fluids, wiring protection, and safety procedures, then inspect for leaks, interference, heat exposure, and secure operation before normal use.
