2 years of development and testing and it was well worth it. Without a doubt the best aftermarket DI injector on the market.

• 2000cc/min at 100bar

• 3000cc/min at 220bar

• 684bhp on E30

• 527whp on E85

• Rock solid, perfectly linear.

• 100% drop-in fitment

• OEM spray pattern

• Stock like cold start and idle

• Just one ECU value change

Every XDI injector set gets tested and matched at three different operating points and comes with full documentation:

1) 0.8ms/20bar for idle stability

2) 10ms/100bar for static flow reference

3) 6ms/200bar for wot performance and stability

The XDI HPFP 35 upgraded fuel pump is HIGHLY recommended to run in conjunction with these. The factory HPFP cannot support the added fueling demands of full e85. 

Custom Tuning is required.

XDI’s roots are deeply in the Bosch Fuel System world. Starting at Bosch in Germany in August 2001, XDI’s founder Uwe Ostmann developed Diesel High-Pressure Nozzles and early faced the challenges of tuning a common rail based high-pressure fuel system.
