Terminator X MPFI Kit Ford Mod Motor 4V

The Holley Terminator X MPFI Kit for Ford Modular 4-valve engines is a complete modern fuel injection and ignition control solution designed for engine builders, restoration specialists, and performance tuners working with Fox-body, SN95, and newer modular Ford platforms. This all-in-one kit replaces outdated carburetor or legacy fuel systems with a fully programmable, engine-mounted control module that manages both multiport fuel injection and ignition timing, eliminating the complexity of standalone aftermarket systems while maintaining street-legal emissions compliance.

At the heart of the Terminator X MPFI Kit lies a 3.5-inch touchscreen engine control module that runs Holley's proven TerminatorX software, allowing real-time tuning, datalogging, and system diagnostics without laptop dependency. The kit includes a factory-style wiring harness engineered for the Ford Modular engine family, which simplifies installation by using OEM-style connectors and routing that fits within factory engine bay constraints. The system's multiport fuel injection calibration is optimized for the 4-valve cylinder head architecture found in 281, 302, 5.0L, and 5.4L Modular engines, ensuring precise fuel metering across idle, cruise, and wide-open-throttle conditions.

This kit is ideal for owners retrofitting carbureted or speed-density fuel systems into restored Fox-body Mustangs, 5.0L swaps into older platforms, or tuners upgrading aging engine management on supercharged and naturally aspirated Modular builds. The included wiring harness significantly reduces installation time compared to custom standalone systems, while the plug-and-play nature makes it accessible to shops with varying levels of tuning experience. Weighing 10.65 lbs and housed in a compact footprint, the Terminator X MPFI Kit mounts cleanly within engine compartments while delivering the datalogging and customization capability previously reserved for high-end race systems.
