If you’re in the market for high-performance 550cc injectors for your SR20DET or KA24DE engine, you’ve come to the right place. Used and approved by RS Enthalpy Tuning, these injectors are a great inexpensive alternative to many of the pricier injectors out there. Enjoy an excellent low pulse width with predictable response, as well as superb atomization for modern single and multi-valve engines. This set will require no more than a 1% trim for easy tuning, and all o-rings are supplied for installation.

Product Features

Each set of 550cc injectors is sold with a complete flow-data chart indicating individual dynamic and static flow rates at 3, 3.5, and 4 BAR at 25%, 50%, and 100% for each injector, along with dead time (latency) period at 14 volts.

As part of our quality control, each injector has been marked/inscribed by our technician with an individual control number, and each is part of a unique flow-matched set.

This injector set is for modified engines with high horsepower. See the chart below.

Injector Body Design: Metal and composite plastic
