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.

As advertised
Color: Green Orange
Did exactly what they needed. Made the remote slightly larger so it is easier to use and less slippery.

Pretty good...
Color: Red
Red color is kind of an orange-red. Hm... Came with some kind of dust on it. Once cleaned off it's not as slippery, yet still slips on just fine. Protects the remote - and your hands from the remote's hard edges. The raised bumps on the back make it easier to pickup - without digging your fingernails into cushions or carpets as you "scoop."

Very handy to have to spot them easily
Color: Dark Blue
Love the cases, have a different color on each rooms tv. Hopefully it will protect from a drop as that is what prompted me to buy it. We cracked the screen on our last remote and they are expensive to replace. Good price
