Spool Performance McLaren M840T RaceCore Injector Harness & ID1050-XDS Injector Package
Upgrade your McLaren M840T fueling system without modifying your factory wiring. The Spool Performance RaceCore Injector Harness is a true plug-and-play solution that allows seamless integration of Injector Dynamics ID1050-XDS injectors while keeping your OEM engine harness completely intact.
Unlike conventional injector upgrades that require cutting, splicing, or repinning the factory harness, the RaceCore Harness connects directly to the OEM engine harness and injector system, simplifying installation and preserving factory serviceability. Should you ever wish to return the vehicle to stock, the original harness remains untouched.
This package includes sixteen (16) genuine Injector Dynamics ID1050-XDS injectors, providing complete replacement of all factory injectors on the McLaren M840T platform. These are the same injectors utilized in our proven high-performance fueling packages and have been extensively validated on both gasoline and ethanol-based fuels.
