Msd street fire coil with 8.5 mm Taylor wires . My v6 pulls nice all the way up to the power band. My car proved it on new Smyrna speedway, I am the car passing everyone. It sure was fun. Utube new Smyrna speedway, pontiac fiero 2015. 5 min. video.

Has anyone used the High Performance Ignition Coil from the Fiero Store. It is red and about $70. Just wondering if it would work better or last longer than the base one. |

When I built the 4.3 in my S-10 pickup, I bought a major name brand high performance ignition coil. I had done other things to the engine at the same time, so I couldn't really tell what changes contributed most to the increased performance. About two years after I had bought it, the S-10 wouldn't start. No spark. I had kept the stock ignition system so I just re-installed it. Honestly, I couldn't tell a difference in performance. I figured I had just wasted my money on this. Later I read an article that explained that a hotter spark can sometimes give the opposite effect as it causes the fuel to "blow away" rather than ignite correctly. Based on my experience, I have just stayed with stock systems. Maybe you could use these dollars on something else.

I thought a hotter spark doesn’t ignite the fuel better, it’s the duration of spark that ignites the fuel better. So there’s a balance between the voltage, resistance of wires and plugs that will make the duration of said spark longer. So a big fat spark doesn’t work as good as a smaller, longer spark event….

Chevrolet Performance has a coil pack in which the coils are much larger than those on the stock coil pack. This may be of some benefit on boosted engines.
