About Product
Get better performance and compliance with precision-engineered fuel injectors for the Lexus SC300. These injectors are made for California-emissions vehicles that are certified by CARB EO# D-126-78. With OEM-spec 14Ω resistance and ±1% flow tolerances, these injectors get rid of P0171/P0300 codes in high-mileage (200k+ miles) Lexus GS300 daily drivers and bring the fuel efficiency back to 21 MPG city/28 MPG highway. SAE J300-validated seals make sure that the car will start up reliably in the cold. This is perfect for Lexus SC300s registered in Alaska or areas where ethanol-blended fuel is used.
Our 60psi-rated injectors can handle turbo increases without leaking for Toyota Supra 2JZGE performance projects. Includes a 12-month guarantee with no mileage limit that restoration shops and fleets trust. -Get CARB-compliant fuel injectors for your Lexus SC300/GS300 today to improve your stock.
Products Advantage
1. Accurate Fuel Delivery for 2JZGE Engines
Our injectors are made just for the 1993–1995 Lexus SC300 and Toyota Supra 2JZGE engines. They use 4-hole laser-drilled nozzles to achieve ±1% flow uniformity, which is 35% tighter than aftermarket options. This gets rid of lean/rich problems (P0171/P0300 codes) that are typical in high-mileage (>150k miles) Lexus GS300 3.0L F/I vehicles. This makes sure that the air-fuel ratios are perfect for both daily driving and forced induction installations.
2. Meets California's CARB emissions standards
they meet California's severe smog rules for 1993–1995 Lexus SC300/GS300 and Toyota Supra JDM imports. Perfect for shops that work in areas where emissions are important, they replace worn OE units directly without needing to recalibrate the ECU.
3. Cold-Start Performance in Arctic Conditions
These injectors stop 1992–1995 Lexus SC300 models from hesitating when they start up in cold weather. They have been tested to work down to -40°F. The Viton®-sealed design keeps the fuel atomization intact even when the engine is idling for a long time in the cold.
4. Durability that resists ethanol
The nickel-plated body and seals that work with E15 fuel don't corrode when exposed to ethanol-blended fuels. This is a very important update for Toyota Supra 2JZGE owners in areas that require biofuel blends. Tested in a lab for 1,200 hours of fast ethanol exposure (ASTM G31).
5. Direct replacement that works right away
These injectors are made to fit directly into the engine bays of 1993–1994 Lexus GS300s. They have the same electrical profile as the OEM ones (14Ω resistance, EV1 connectors), thus they work well with original ECUs without the need for wire adapters or tuning.
6. Protecting coastal vehicles from corrosion
These injectors have salt-spray-certified coatings (ASTM B117) that keep seawater from corroding them. They are perfect for Lexus SC300s and Toyota Supras that are driven every day on the California/Texas Gulf Coast.
7. Design that doesn't leak at high pressure
Laser-welded injector bodies can handle fuel pressures of up to 60 psi without leaking. This means they can be used with aftermarket turbo systems for 2JZGE performance builds. Tested for more than 200 cycles at WOT.
Main application scenarios
Keeping the fuel efficiency of the family car up
Models that work with it: 1993–1995 Lexus SC300 (2JZGE 3.0L F/I)
Pain Points: Old injectors that make the car get bad gas mileage (15–18 MPG) and make black smoke when the car starts up cold.
Our Lexus SC300 fuel injector fixes the factory fuel efficiency (21 MPG in the city and 28 MPG on the interstate) by improving atomization. This is great for family cars that meet California emissions standards. Cut down on your monthly gas bills and pass smog tests with ease.
Improving the smoothness of the engine throughout the daily commute
Models that work with it: Lexus GS300 from 1993 to 1994 (Vin J 2JZGE)
Rough idling and low-speed hesitation (P0300 codes) are problems with high-mileage (200k+ miles) commuter automobiles.
±1% flow constancy keeps the air-fuel ratio steady, making it suitable for Lexus GS300 3.0L daily drivers who have to stop and go a lot. It makes acceleration smooth again and cuts down on cabin vibrations.
Diagnosing and fixing critical failures quickly
Compatible Models: 1995 Toyota Supra (2JZGE California Emissions)
Pain Points: Clogged injectors that cause misfires (Cylinder 3/6) or damage to the catalytic converter (P0420 codes).
The solution is to use direct replacement fuel injectors for the 1995 Toyota Supra that have laser-drilled nozzles that eliminate obstructions. This makes it possible to fix the car on the side of the road in 30 minutes. Keeps you from having to pay for expensive ECU reprogramming and towing.
High-Mileage Vehicle System Overhaul
Compatible Models: Lexus SC300 and GS300 from 1992 to 1995 and Toyota Supra from 1993 to 1995
Problems: OEM injectors that are worn out, which causes power loss (0.5 seconds from 0 to 60 mph) and emissions that don't pass (high HC levels).
Full 6-injector replacement kit for old JDM engines, including 1,200 hours of data showing how long it will last. Restores the performance of 30-year-old Lexus SC300/GS300 and Toyota Supra 2JZGE cars to almost new.

Frequently Asked Questions
1. What kinds of cars can these fuel injectors work with?
+
-
These direct-fit injectors work with the 1993–1995 Lexus SC300 (2JZGE 3.0L F/I), the 1993–1994 Lexus GS300 (Vin J), and the 1993–1995 Toyota Supra 2JZGE engines, including the ones that meet California emissions standards.
2. Will these injectors turn on the check engine light?
+
-
No. They have OEM-spec 14Ω resistance and ±1% flow tolerances, which means they work like the factory electrical profiles. This stops codes like P0171 (lean condition) or P0300 (random misfire) from showing up in high-mileage Lexus GS300/SC300 vehicles.
3. Can you use them in California?
+
-
Yes. These injectors are certified under CARB EO# D-126-78 and meet severe emissions criteria for California-spec 1993-1995 Lexus SC300/GS300 and Toyota Supra automobiles.
4. After I install it, do I need to reprogram the ECU?
+
-
Not needed. They are made to be plug-and-play replacements, so they work perfectly with factory ECUs in Lexus SC300 daily drivers and modified Toyota Supra 2JZGE builds.
5. How do they do in cold weather?
+
-
These injectors include SAE J300-validated seals that stop cold-start reluctance down to -40°F. They are perfect for 1992-1995 Lexus SC300s that are driven in Alaska or Northern Europe.
6. Can they work with fuels that have ethanol in them?
+
-
Yes. The nickel-plated body and E15-resistant Viton® seals can handle ethanol corrosion, so they work with the Toyota Supra 2JZGE in places where biofuel mixes are required.
7. How long do you think it will last?
+
-
These injectors can last 100,000 miles, which is three times longer than remanufactured ones for Lexus GS300 restoration projects. They were dynamically tested at 25Hz firing rates (8,000 RPM simulations).
8. Can they handle turbo upgrades from other companies?
+
-
Yes. The laser-welded body can handle 60psi of fuel pressure, therefore it can accommodate turbocharged installations in 2JZGE performance builds without leaking or losing flow.
9. How quickly do you need to replace P0420 codes?
+
-
It's really important to utilize it right away. OEM injectors that are clogged in a 1995 Toyota Supra can often break catalytic converters, which cost more than $1,200 to fix. Our injectors stop the buildup of particles that might cause P0420 failures.
