Fuel System Support for the G16E-GTS: DeatschWerks 1100cc Injectors for GR Yaris and GR Corolla
The DeatschWerks DWK17MX-12-1100-3 is a matched set of three 1100cc per minute fuel injectors engineered specifically for the G16E-GTS 1.6L turbocharged three-cylinder engine found in the 2020+ Toyota GR Yaris and 2023+ Toyota GR Corolla.
The unique three-cylinder layout of the G16E-GTS requires a set of three injectors rather than the four-cylinder configurations found in most other high-performance platforms, and the DWK17MX-12-1100-3 is purpose-built to match.
Manufactured in the United States and Germany from precision-machined components, DeatschWerks 1100cc injectors support ethanol fuel blends including E85, providing the fuel delivery headroom needed for significant power upgrades, port injection additions, or aggressive E-content tuning on these rally-derived platforms. Each injector is individually matched for flow balance and includes the data set needed for proper calibration by a tuner.

Frequently Asked Questions
What is the DWK17MX-12-1100-3?
The DWK17MX-12-1100-3 is a DeatschWerks matched set of three 1100cc per minute fuel injectors designed for the Toyota G16E-GTS 1.6L turbocharged three-cylinder engine in the 2020+ GR Yaris and 2023+ GR Corolla. The set is E85 compatible and includes a 3-year DeatschWerks warranty.
Why does the GR Yaris and GR Corolla need a set of 3 injectors?
The G16E-GTS engine is a turbocharged inline-three cylinder, requiring only three injectors rather than the four found in most other performance platforms. The DWK17MX-12-1100-3 is specifically designed as a three-injector set to match this engine configuration correctly.
Does DWK17MX-12-1100-3 support E85 on the GR Yaris?
Yes. The DWK17MX-12-1100-3 is compatible with E85 and other high-ethanol content fuel blends. At 1100cc/min flow capacity, these injectors provide substantial fueling headroom for E85 calibrations with supporting upgrades on the GR Yaris and GR Corolla G16E-GTS platform.
Do I need a tune after installing DWK17MX-12-1100-3?
Yes. Upgrading to 1100cc injectors from the factory units requires a professional ECU tune to properly calibrate injector timing, pulse width, and fuel delivery. Installing DWK17MX-12-1100-3 without a corresponding tune will result in improper air/fuel ratios and should not be driven without tuning.
Will DWK17MX-12-1100-3 work on a stock GR Yaris?
The DWK17MX-12-1100-3 can be installed on a stock GR Yaris, but the 1100cc flow rate significantly exceeds factory requirements. These injectors are best suited for builds with a turbo upgrade, port injection conversion, or other supporting modifications combined with an E85 or high-power calibration.
What warranty comes with DWK17MX-12-1100-3?
DeatschWerks includes a 3-year warranty with the DWK17MX-12-1100-3 against defects in materials and workmanship.
Are the injectors in DWK17MX-12-1100-3 individually tested?
Yes. DeatschWerks tests and flow-matches each injector individually before shipping. The matched set in DWK17MX-12-1100-3 ensures balanced fuel delivery across all three cylinders of the G16E-GTS engine.
Can DWK17MX-12-1100-3 be used with port injection on the GR Corolla?
Yes. The DWK17MX-12-1100-3 is compatible with port injection setups on the GR Corolla. Running port injection in addition to or in conjunction with modified direct injection is a common approach on the G16E-GTS for achieving high power targets with E-fuel blends.
Installation Instructions
- Allow the engine to cool completely and depressurize the fuel system before beginning.
- Disconnect the battery and locate the fuel injector rail on the G16E-GTS engine.
- Disconnect the injector electrical connectors from all three factory injectors.
- Release the fuel rail retaining clips or bolts and carefully remove the rail with the factory injectors attached.
- Remove the factory injectors from the fuel rail, noting o-ring position.
- Lubricate the new DWK17MX-12-1100-3 injector o-rings and press each injector into the fuel rail.
- Reinstall the fuel rail with the new injectors seated into the intake manifold ports.
- Reconnect all electrical connectors and torque fuel rail fasteners to specification.
- Reconnect the battery and cycle the ignition key several times to prime the fuel system before starting.
- Have the ECU calibrated by a qualified tuner before operating the vehicle under load.

Fuel Injector Connectors
Fuel injector connectors are the electrical interface between the engine wiring harness and each individual fuel injector solenoid, carrying the precision pulse-width-modulated signal from the ECU that controls injection timing and duration. Connector failure, corrosion, or poor terminal contact causes intermittent misfires, rough idle, and lean conditions that are frustratingly difficult to diagnose without testing each injector circuit individually. Replacing damaged or corroded injector connectors with new pigtail harnesses using factory-grade terminals restores clean electrical contact and eliminates ghost faults that confound standard scan tool diagnostics. Builders doing engine swaps or injector upgrades also rely on connector pigtails to adapt factory harnesses to new injector styles without permanently altering the original wiring. Popular Upgrades Top-selling injector connectors include Delphi and Bosch OEM-spec EV6 connector pigtails for late-model GM, Ford, and Chrysler E...

Fuel Injector Sets - 3Cyl
A matched set of fuel injectors ensures balanced fuel delivery across every cylinder in 3-cylinder engine applications, preventing the cylinder-to-cylinder variation that causes rough idle, uneven power distribution, and difficulty achieving correct air-fuel ratios across the entire rev range. Factory injectors lose flow capacity and spray pattern quality over time due to deposits, coking near the injector tip, and solenoid wear, making a complete set replacement more reliable than swapping a single injector after a misfire diagnosis. Flow-matched injector sets are especially important on high-performance builds where uneven fueling translates directly into inconsistent combustion and wasted tuning effort. Whether replacing worn OEM injectors or stepping up to a higher flow rate for a forced induction build, buying a matched set is the correct approach for consistent results. Popular Upgrades Top-selling 3-Cylinder injector sets include Bosch EV14 matched sets for turbocharged appli...

Fuel Injectors
Fuel injectors are the precision metering devices at the heart of every modern electronic fuel injection system, responsible for atomizing fuel into a fine mist at exactly the right moment, duration, and spray angle for complete combustion. As injectors age, internal deposits and solenoid wear cause flow rate deviation, tip coking, and spray pattern degradation that result in rich or lean cylinder conditions, rough idle, elevated emissions, and reduced fuel economy. Selecting the correct replacement or performance injector requires matching the flow rate, impedance, connector type, and spray angle to your specific engine and fuel system configuration. From factory-replacement units restoring a daily driver to high-impedance Injector Dynamics sets supporting four-figure horsepower builds, this collection covers the full range of fuel injector needs. Popular Upgrades Top-selling fuel injectors include Bosch OEM-replacement and remanufactured injectors for high-volume domestic and impo...
