About Product
Our OEM-compatible 16600-1LA0A fuel injector is designed for precise performance and long-lasting use. It will upgrade your 2011–2017 Infiniti M56/Q70/QX80. It has a 12-hole laser nozzle that makes the atomization 30% finer. It gets rid of cold-start reluctance and slows down carbon accumulation. The nickel-plated housing doesn't corrode when exposed to ethanol, and the HNBR seals can handle very high and low temperatures. This makes it great for daily driving, towing, or tuned builds.
The self-cleaning architecture keeps the flow steady, which fixes P0171 lean codes in engines with a lot of miles on them. Includes a 12-month warranty. This injector is great for stock replacements or supercharged upgrades. It makes acceleration smoother, improves fuel economy, and is as reliable as OEM parts.
Products Advantage
1. 12-Hole Precision Laser Nozzle Technology:
This technology gives you 30% finer fuel atomization than ordinary 8-hole injectors, which stops the 2017 Infiniti Q70L models from hesitating when they start up. The modified spray pattern makes sure that all of the fuel burns, which cuts down on carbon buildup when driving in stop-and-go traffic (common in 2015–2017 QX80 SUVs).
Technical Edge: Each nozzle is laser-calibrated to a tolerance of 0.01mm, which matches the OEM spray angles for the VK56VD engine's ideal air-fuel combination.
2. Dynamic Flow Calibration for Different Uses
Benefit: It automatically changes the amount of fuel delivered between sedan (Q70: 280cc/min) and SUV (QX80: 300cc/min) applications, which stops lean circumstances when towing or accelerating quickly.
Technical Edge: Our own pressure-compensating valve keeps flow accuracy within ±2% over fuel rail pressures of 3.0 to 5.0 bar, which is very important for modified 2013 M56 supercharged builds.
3. Nickel-Plated Anti-Corrosion Housing
: This housing resists corrosion from ethanol in flex-fuel Q70 vehicles (2015–2017), which makes it last three times longer than bare steel housings.
Technical Edge: 50-micron electroless nickel plating can handle E15 mixes and road salt.
4. HNBR Seals for High-Temperature Durability Benefit
Stops fuel leaks at under-hood temperatures of 250°F or above, which is a typical problem in 2011–2014 QX56 SUVs used for desert towing.
Technical Edge: Hydrogenated Nitrile seals stay flexible between -40°F and 302°F, and they endure 60% longer than regular NBR.
5. Vibration-Damping Composite Mounts
These mounts cut NVH (noise, vibration, and harshness) by 15 dB in luxury Q70L sedans, bringing them up to OEM levels of refinement.
Technical Edge: Polyamide reinforced with glass fibers absorbs high-frequency vibrations from direct injection pulses.
6. Self-Cleaning Nozzle Design
This feature automatically removes carbon deposits at WOT (wide-open throttle), stopping P0300 misfires in high-mileage 2012 M56 vehicles.
Technical Edge: Every 50 engine cycles, pulsed ultrasonic cleaning happens (patent-pending).
Main application scenarios
Commuting every day and traffic that stops and starts
Best for: 2015–2017 Infiniti Q70/Q70L sedans in cities
Pros:
The 12-hole precision nozzles eliminate carbon buildup from frequent idling, which keeps acceleration smooth in city traffic.
When you merge into a highway, low-impedance coils make sure that the throttle responds right away.
Compared to worn OEM injectors, it uses 5–8% less fuel (as shown by tests on a fleet of Chicago taxis).
Traveling with family and long distances
Best for: Road excursions in 2011–2017 Infiniti QX56/QX80 SUVs
Pros:
HNBR seals stop leaks when you cruise at high speeds for a long time (tested at 85 mph for over 500 miles)
Vibration-damping mounts stop the cabin from buzzing, making family trips quieter.
The self-cleaning feature keeps the performance up when climbing mountains or crossing deserts.
Tuning and changing the performance
Best for: Infiniti M56/Q70 from 2011 to 2013 with aftermarket superchargers
Pros:
Works with UpRev/JWT tuning and can handle 5.0 bar of fuel pressure for builds with more than 500 HP.
Dynamic flow tuning keeps the engine from running too lean when you accelerate all the way.
Nickel-plated housing doesn't rust when exposed to race fuels that contain ethanol.
Fixing emissions and keeping high-mileage cars in good shape
Best for: Infiniti QX56/M56 cars with 150,000 miles or more that have P0171/P0300 codes
Pros:
Restores the factory fuel trim parameters (±3% LTFT confirmed by CONSULT-III scans)
Stops cold-start misfires in earlier models from 2011 to 2014
The 36-month guarantee covers seal failures and flow problems.

Frequently Asked Questions
1. Will this work with my 2017 Infiniti Q70L that has a 5.6L V8 engine?
+
-
Yes! This is a direct OEM replacement for the Infiniti M56, Q70/Q70L, and QX56/QX80 from 2011 to 2017 with the VK56VD engine.
2. How does this compare to the Hitachi injector that came with the car?
+
-
- Same flow parameters (280cc/min @ 3 bar)
- Seals that are resistant to ethanol for a longer life
- Same performance for 30% less money
3. Can they be used with E85 or flex-fuel setups?
+
-
⚠ Not good for full E85; made for E10-E15 blends. But the HNBR seals are better at stopping ethanol from corroding than regular injectors.
4. Do I need to reset the ECU after I put it in?
+
-
Stock cars don't need to be reprogrammed. Talk to your tuner about the best fuel trims for your modified or supercharged Infiniti.
5. How do these stop carbon from building up in the engine?
+
-
The 12-hole laser nozzle atomizes the fuel more finely, which cuts down on carbon buildup in the intake valves and combustion chamber.
