Overview:

The MSD Smart Coil Big Wire Kit allows you to run dwell time over 5 milliseconds to gain the most of the Smart Coils. It will allow the coil to produce 50,000 peak voltage and peak energy of 190 millijoules, this means you get hotter spark at the plug to burn the maximum amount of fuel in each cylinder to reach the optimal horsepower out of your engine. It is compatible with Holley EFI and many other aftermarket electronic fuel injection systems and will run on traditional 12 or 16 volt electrical systems found in race applications. Unique elongated mounting holes accommodate IGN-1A mounting brackets or allow it to bolt in place of an LS coil with 72mm bolt spacing. The MSD Smart Coil will bolt right on to Holley LS cast aluminum valve covers for a super clean look. Available in red or black.

  • Contains two terminated harnesses with 7-pin connector for easier plug-in to Holley LSx main harness or factory GM LSx harness
  • The harnesses are labeled for different engine types for GM and Ford cylinder banks even Holley universal coil near plug harness

Satisfied with color and fit
Size: Small, Color: Light Purple
For the money, this is a good shirt. True, the material is a bit thin and there is a feeling of 'fragility' (loose threads here and there) but the color is nice, the texture is appropriate. The sizing is what I call "New American". I was a medium my whole life but supersizing has made me into a small. I haven't changed, Americans have grown bigger. I am six feet tall and a bit (180+ cm) and weigh 155 pounds (70kg and a bit). The small fits me just fine everywhere but the shoulders are just barely wide enough. If you have slightly wider shoulders but are similar to me otherwise, this may be too tight for you in that one place.

Fits too tight at waist.
Size: XX-Large, Color: Wine
Quality of product satisfactory, however size labeling incorrect. I ordered a XXL that is too tight at the waist. It should be labeled XXL Trim.
