Not your off the shelf Bosch injector. Beware of companies selling similar looking injectors for less. Most are not flow matched or balanced beyond what Bosch does at the factory. This can cause all sorts of issues with tuning, drivability, and safety. Is your motor worth risking?

These are among the most advanced injectors available with incredibly fast response and industry leading atomization.

Available in 38mm, 48mm, and 60mm heights to fit a wide variety of applications.

Injectors are Flow-matched and can be custom fit to almost any US domestic, European import or Asian import application.

• We supply all required o-rings, seals and adapters to properly fit your specific engine application. • Free electrical connector pigtails are included to allow for an easy soldering installation to your existing wiring harness. • “Plug and play” two-sided electrical connector adapters can be purchased separately and can be found on our “connectors and adapters” page.


This is a modified fuel injector – We custom mill brand new American-made fuel injector cores in large-quantity batches to achieve the highest quality product.

Compatable with all fuels
This is a high performance, high volume fuel injector. These injectors have been highly modified and flow-matched to specific specifications. The fuel delivery is from a single-hole ball/disc-type fuel nozzle – -cone spray for maximum fuel atomization.
High impedance (no inline resistors or resistor box requires for use)
These will perform upto 8 bar of fuel pressure. Excellent low pulse width response with predictable, lightening-fast response. Excellent fuel atomization for modern multi-valve engines.
Flow rates: 650 cc/min – 3.0 BAR (43.5 psi) 710 cc/min – 3.5 BAR (50.8 psi) 766 cc/min – 4.0 BAR (58.0 psi)

Complete static and dynamic flow information with each set. Plus correct injector latency, full injector data supplied for all gm vehicles in either hp tuners or efi live format.
Electrical connector type: EV6/EV14/USCAR
