ACCEL Set-Of-Eight 'Coil-On-Plug' Style Ignition Coil Packs for 2005-2010 4.6L 3V GT Mustangs.
Intended for Ford's 4.6L 3-valve V8 engine, these coils feature advanced bobbin technology, highly specialized silicone magnetic steel cores, along with optimized winding, resistance and turns ratios to delivery 10-15% more energy than the OEM coils.
Specialized high temperature epoxy resists shock and vibration, while increasing thermal conductivity. These are direct plug replacement for OEM coils. They feature bodies and/or secondary towers molded in ACCEL yellow and feature brass secondary contacts (except direct fire coil on plug applications).
*Sold as a set of eight; a car requires eight.

I was skeptical of improved performance claims, and purchased the coil set mainly for cosmetic purposes. The yellow casing goes perfect with Mustang Screaming Yellow and chrome valve covers. After several months it's still difficult to notice any significant performance gain under normal driving conditions. However, when hitting the throttle hard the new coils seems to get a better/meaner response from the Ford Racing Supercharger.
