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 21-2001-SF. 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.

Ignition Coils
Ignition coils take 12 volts from the battery and step it up to the 30,000 to 60,000 volts your spark plugs need to fire under compression. When a coil weakens, the cylinder it feeds misfires under load, throws a P0301 through P0308 code, and drags fuel economy down. This collection stocks direct-fit OEM replacements and high-output performance coils for domestic, import, and JDM platforms. Every coil here comes from a name the shop trusts. Granatelli Pro Series 60KV, MSD Blaster and Xtreme COP, aFe SCORCHER, Mishimoto Race Series, Cusco Type-2, HKS Super Fire Racing Coil Pro, and OE-quality Motorcraft, ACDelco, and Denso units, matched by year, engine, and coil style. Coil-on-Plug, Coil Packs, and Cassette Coils Modern engines run one of three ignition-coil layouts. Coil-on-plug (COP) mounts a dedicated coil on top of every plug, which is what you find on most trucks and performance cars built after roughly 2005. Coil pack systems drive two or four plugs from a single unit, co...
