Black, 8-Pack

Overview
These Holley EFI Smart Coils are a bolt-in ignition upgrade for your late model HEMI or Coyote engine. Here's the difference over a stock coil; they produce more spark energy while consuming less power without sacrificing voltage output. This means you get hotter spark at the plug to burn the maximum amount of fuel in each cylinder while using less power from your electrical system. For Hemi combinations currently using Holley EFI or Terminator X, use Smart Coil Ignition Harnesses 558-312 Coil Extension Harnesses 558-326 for a plug and play solution.

  • Engine specific kits include a direct bolt-on billet aluminum pick up bracket
  • Rigid mounting that will not flex and cause timing fluctuation
  • Easy to install much like traditional MSD Crank Trigger Kits
  • Included installation instructions cover mechanical setup and provide step-by-step Holley EFI Software Setup

Orange looking, but large capacity
Size: One Size, Color: Brown
I ended up returning this product, it looks more orange in color than what is pictured. Also, it doesn't smell like leather. On a positive note, it was inexpensive and did have a large organization capacity.

Best wallet on the market.
Size: One Size, Color: Nubuck Black, Size: One Size, Color: Nubuck Black
This is the only wallet I buy now. Over and over. I like simple wallets. No bifold. Trifolds hurt your back. Hard case are a mess that rub your credit card mag strips off from friction. I found this a few years back and have bought 3. I am a stone worker so mine get worn from the dust and grit in my pockets faster than normal wear and I need to swap them out every couple of years. I like the simplicity and the fact that the pockets are stitched the same depth so your cards stack like varying length stair-style tabs rather than all the same depth. Wallet is RDIF protection lined. I can put like 15 cards in this wallet and it’s still thinner than a bifold holding 5. I love it. I mean it. I haven’t found a better wallet than this one. They are very well-built. Picture shows wallet with 19 cards + 40 dollars. 3/4 of an inch thick.

Good Product
Size: One Size, Color: Smooth Finish Black
Good product although the leather is a bit stiff. Hopefully it will soften up over time. Fair price, fast shipping…
