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
  • More spark energy than any other IGN-1A smart coil on the market for maximum fuel burn during combustion sequence

Works with Mac!
Style: 34" WQHD Curved 100Hz USB-C Docking
This monitor is great. I was suprised on how light it was, as I have a large Asus monitor that is very heavy. I am very happy with quality and it works great with a Mac.

Just a great monitor
Style: 34" WQHD Curved 100Hz USB-C Docking
What a difference. I purchased this screen to replace an older screen. I knew I would see some differences as the screen was a larger size. What I did not expect was the picture quality. It is exceptional. The colors appear to be accurate. Based on the build quality I expect it to be very durable. It has been very capable of running my games. This has been a great purchase.

Didn’t power on, still waiting. . .
Style: 34" WQHD Curved 100Hz USB-C Docking
I received this brand new monitor. It would not power on Amazon did not have any more in stock so it was sent directly to the manufacturer for repair. They have had it for two weeks and are going to have it for another one to two weeks before shipping it back to me and hopefully I’ll actually get to try it out I really hope it’s worth it in the end! Seriously frustrating that a brand new monitor would not even turn on and it’s gonna be at least a month before I even get to try it.

Meh....
Style: 34" WQHD Curved 100Hz USB-C Docking
Milktoast stats--right down the [lower] middle of the line. 1ms reponse time, mediocre 100Hz max refresh, and NO FreeSync support. Hardly expensive, it still is quite a bit more than other monitors with MUCH better specs, but less brand name recognition. I think the only reason it is so expensive is the white treatment. The VESA mount in the back did not fit my VESA plate. One side of the plate sat up on a small ridge of plastic. Not a showstopper, but hardly ideal--or necessary. The bezel (or rather, the DEAD PANEL SPACE between the bezel and the displayable area of the panel) is HUGE. Like 1/4" on the sides, and 1/8" on the top/bottom. If you're going to make a thin bezel, then make an edge to edge display. Otherwise, just give me a frame so that my image displays edge to edge. To me, it looks like the old CRT monitors from the 90s... YECK!
