Dorch Engineering DE1500 Fuel Injectors - BMW F20 M140i | F22 M240i | F30 340i | F32 440i (B58 Gen1)

The Dorch Engineering DE1500 is a true ground-up upgraded direct injector for the Gen1 B58, developed in partnership with Stanadyne rather than being a modified OE injector. The result is a Tier 1 OEM-quality drop-in injector optimised for performance use and alcohol-based fuels.

A more efficient magnetic design gives excellent ballistic control at low pulse widths and, combined with full control over the spray pattern, allows around 70% more flow than stock while retaining standard idle quality and drivability on both pump fuel and E85.

Please note:

• Software changes are required to run these injectors. Bootmod3, MHD and MG Flasher support is coming soon; otherwise a custom WinOLS calibration will be needed.
• Only suitable for Gen1 B58 vehicles up to the 2019 model year – not compatible with Gen2 B58 vehicles.
• Power figures are conservative averages – tuning plays a big role in the power potential of a DI system.

Features

• Flow rate: 1550cc at 200 bar (vs 900cc stock)
• Flow capacity: approx. 1050whp on petrol, 900whp on E50, 800whp on E85 (vs 675 / 600 / 520whp stock)
• Approx. +70% flow over the standard injectors
• Stock drivability and idle on E85 and pump fuel
• Improved E85 compatibility over stock
• Plug and play fitment with OEM-level "drag and drop" calibration
• Perfectly batched sets with Tier 1 OEM quality control
• Dorch Engineering lifetime warranty
