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.

Fits my 2026 civic sport perfect!
Size: AF151
No issues, fitment is perfect. Great quality for an excellent price. Dealer wanted like $24 for a basic one. Nah I'm good I'll just go on Amazon and get it for $8. Took 30 seconds from start to finish can't get any easier.

Fits well and installs easily.

This filter looked about the same as the OEM filter. It installed in about a minute. The quality appeared to be fine. It was protected in a cardboard box. It fit my 2014 Subaru Outback perfectly. I just installed it an hour ago so I don’t have any long term observations about longevity or effectiveness. I can’t see any reason why it would not work as well as the original, it seemed identical.

Great fit and quality
Size: AF113
Not a complicated product, but after going to 2 different auto parts stores and this not being in stock, Amazon to the rescue. Arrived the next day and the quality is definitely on par with “store brand” ones from retailers. Definitely cheaper as well.
