🔥 Proform 66943C: Unleashing High Performance with the 50,000 Volt HEI Coil Review

This high performance ignition part was exactly what my automotive engine needed. I noticed a significant improvement in power and acceleration right away. The installation was easy and the price was reasonable. It truly lives up to its high performance reputation.

This coil has excellent performance. Unfortunately it didn't work. The yellow wire was severely bent when starting the engine.

Item as described, easy fit, 10 minute job. My only issue was that the packaging it came in wasn't actually sealed. I was lucky that the "box" came to my house with the part inside. The delivery was on the date indicated, but it still took a long time to position the order. I'll update my rating after driving for a while to see if there's a jump in miles per gallon and horsepower. The old coil was stock and rusted everywhere so this should be a great upgrade for my '81 El Camino.
