ACCEL coils feature an advanced Bobbin technology, highly specialized silicone magnetic steel cores, along with optimized winding, resistance and turns ratios to deliver 10 – 15 percent more energy than the stock factory OEM coils. More energy equals a hotter spark that burns fuel more completely releasing all it’s potential energy translating into better fuel economy and more power that you can feel.

Stick to stock. Dropped 91hp on these compared to the msd coils. Was hoping to find a better coil option since the msd coils keep going out one at a time, but this isn’t it. Keep the factory coils best bet. These coils first dyno pass put down same as msds 441hp mext pass 359 next 351 after they warmed up they just weren’t keeping up at higher rpms. Put msd back on and problem gone.
Not a direct bolt on, but they work Bottom line first; these were not a direct bolt-on fit, I needed to go to the hardware store and purchase 0.5inch spacers and 0.5inch longer bolts. These work great; increased throttle response (horsepower/torque) and increased fuel efficiency (2-4mpg), exactly what I was looking for.Depending on which website you go to you will get conflicting information as to the fitment of these coils. My application was for a 2004, Chevy Silverado 2500, 6.0 liter. Many sites said these would not fit,…
excellent automotive product I had two problems with my engine . 1) Engine was shaking 2) acceleration was slow & unable to achieve maximum performance . Both of these problems are now solved . Also my cold weather start ups are instant ( temps are in the middle 20’s ) . I did not have a problem starting in the cold weather , but it now start faster than before .
