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.

Ok
Size: 5.25 inch (Pack of 1)
My pups not overly interested in it. If it had some texture it would be better. The price was right though, and it gives him some variety in his toys.

durable. interesting shape
Size: 9.5 inch
I like that chew bones come in a variety of shapes. This shape is currently not my dog's favorite but that is ok. She plays with it a bit. It is durable and she will get around to it sometimes.
