ID1050-XDS, for P1, direct replacement, no adapters, 14mm lower o-ring, set of 8.
The ID1050-XDS is the evolution of the ID1050x.
The ID1050-XDS benefits from Dual Slope Matching, a method of matching the flow rate in both the linear, and nonlinear operating range, providing better cylinder to cylinder consistency at low pulse widths.
Corrosion resistant internals make it compatible with all known fuels, capable of extended service life with corrosive fuels.
Compact body allows fitment in 200+ applications, including current and future engines utilizing short body injectors.
Stronger magnetic circuit offers stable operation up to 10 bar.
Replaceable inlet filter extends service life.

The ID1050-XDS injectors deliver precise fuel control and excellent atomization, making them ideal for high-performance McLaren P1 engines. They improve throttle response, fuel efficiency, and maintain smooth drivability even under extreme power demands.
Yes, these injectors are designed as a direct-fit replacement for the P1's factory fuel system. Proper ECU tuning is necessary to optimize injector scaling and maximize performance.
Absolutely. The ID1050-XDS injectors are fully compatible with E85 and other ethanol blends. Their corrosion-resistant construction ensures reliable performance for flex-fuel and high-output applications.
With proper tuning and supporting fuel system upgrades, the ID1050-XDS injectors can support moderate to high horsepower gains beyond stock, suitable for track-focused or high-performance builds.
For mild to moderate performance builds, the stock fuel system may suffice. For higher-power or ethanol-based setups, upgrading fuel pumps, lines, and fuel management components is recommended to maintain stable fuel delivery and consistent injector performance.
