Product Details

The MSD 8740 Coil Current Booster is a quick and easy solution for increasing ignition power on Ford Modular engines. This performance upgrade delivers 20% more current over stock to the ignition coils, resulting in increased spark energy at the spark plugs for improved combustion and engine performance.

Key Features:

Increases coil current by 20% over stock output for enhanced spark energy
Factory-style wiring connectors plug directly into stock coils and harness for easy installation
Built-in Two-Step rev limiter for consistent launches and improved 60-foot times
Designed specifically for Ford Modular engines
Improves throttle response and high-RPM performance

This coil current booster is ideal for naturally aspirated or forced induction applications where additional ignition energy is needed to reliably ignite air/fuel mixtures. The integrated Two-Step rev control allows you to set a lower launch RPM for better traction and more consistent starts at the drag strip.
