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.

Features:
  • Most accurate way to trigger your electronic fuel injection (EFI), can be installed as 12-1 or 12x
  • Powerful magnets embedded in a 3/8-inch thick billet 6061-T6 aluminum trigger wheel
  • 3-wire Hall-Effect Sensor that is not easily susceptible to EMI/RFI Interference
  • 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

Works great with tennis balls
I have a pretty large yard, and this thrower is great for my little Jack Russel puppy. It even picks up ball without having to touch all the spit.

Thing is absolutely garbage. Ball didn’t make it back once! Broke in half
Junk and they don’t follow through with the shipping that they claim. Said between 7am and 11am. Don’t post it if ya can’t fulfill your shipping expectations

Good toy for dogs
This is a great toy! I do wish the handle was a little longer because I do not have a lot of upper body strength due to health issues. I can still throw with this further than I can without the launcher so my dogs really love it and get excited any time I get this out!
