DeatschWerks Performance Fuel Injector Set - 550cc

Product Details

The DeatschWerks 550cc Fuel Injector Kit provides the essential fueling foundation required for moderate forced induction or high-output naturally aspirated builds. While many aftermarket injectors sacrifice idle quality for raw flow, the 18U series maintains excellent low-pulse-width linearity. This means your vehicle will retain a smooth, factory-like idle and clean part-throttle transitions while still having the overhead to support increased boost or aggressive cam profiles. It is an ideal upgrade for drivers who demand reliability and precision without the "bucket-and-funnel" inaccuracy of budget-tier injectors.

Key Features

• Dynamic Flow Balancing: Unlike many competitors who only test static flow, DW tests at various pulse widths to ensure balance throughout the entire RPM range.

• High-Pressure Stability: Capable of maintaining accurate delivery even under increased fuel pressure environments.

• Direct Fit Fitment: Specifically engineered for the 14mm fuel rail bores common in many modern performance engines.

• Advanced Atomization: Features a specialized nozzle plate that breaks fuel into a fine vapor, leading to more efficient combustion and better throttle response.

• In-House Quality Control: Each unit is processed and tested at DeatschWerks’ facility in Oklahoma City to maintain strict US-based quality standards.
