Review on πŸ”₯ Street Fire Ignition Control Box MSD 5520 - Black by Michael Maes

Revainrating 5 out of 5

Good zap for the money

Installed on a '79 Ford F150 with a 351Nm engine. Noticed immediate improvement in idle and throttle response. I live at 7,000 feet so I'll try anything to help the big block. A blaster coil is also installed. A word of caution, the box is very heat sensitive and will shut down. The original installation was too close to the heater hoses.

Pros
  • Stylish and modern design
Cons
  • So far so good
